ABSTRACT

Introdução: no Brasil, a utilização de fitoterápicos e plantas medicinais é uma prática amplamente difundida, todavia, o consumo destes compostos em associação com medicamentos alopáticos caracteriza um risco à saúde devido às potenciais interações medicamentosas e seus efeitos. Objetivo: analisar as potenciais interações envolvendo fitoterápicos e plantas medicinais com medicamentos alopáticos na população de Rondonópolis, MT. Metodologia: trata-se de um estudo transversal de base populacional com 370 participantes. Os dados foram coletados em visitas domiciliares com um instrumento estruturado e padronizado. Para identificar as potenciais interações foi utilizada a base de dados Medscape® e a literatura nacional e internacional. Resultados: 131 (35,40%) indivíduos informaram consumir plantas medicinais e ou fitoterápicos concomitante a medicamentos alopáticos. A interação entre fitoterápicos e medicamentos alopáticos mais frequente foi entre Passiflora incarnata e cinarizina, para plantas medicinais foi entre hortelã e sinvastatina. As consequências mais prevalentes decorrentes das interações foram a intensificação da depressão do Sistema Nervoso Central, o aumento da anticoagulação e o risco de hipoglicemia. Conclusão: os dados analisados no presente estudo possibilitaram identificar potenciais interações existentes entre medicamentos alopáticos e plantas medicinais/fitoterápicos na população de Rondonópolis-MT e apontam para a necessidade de se estimular o uso racional da fitoterapia no âmbito da saúde pública.

ABSTRACT

The carpel is the female reproductive structure composed of a set of stigma, style and ovary. Normally passionflower have three carpels, however, some cultivars have this structure in greater quantity. The objective of this work was to identify relationships between the number of carpels and the physical characteristics of BRS Gigante Amarelo fruits. The flowers with three and four carpels were marked, pollinated and the fruits harvested from these flowers analyzed for transverse diameter, longitudinal diameter, pericarp thickness, fruit mass, pulp mass, pulp ratio, number and weight of seeds. A completely randomized design with 10 replicates per treatment was used and each plot had the average of 3 fruits. The data were submitted to variance analysis and the means were compared by the Tukey test at 5% of probability. The fruits generated by flowers with 4 carpels were 18,30% heavier, their pulp were on average 20.75% heavier, presented transverse diameter 7,53% superior to that of fruits generated by flowers with 3 carpels. Similar increments were identified regarding the number of seeds and the weight of seeds per fruit that increased 18,85% and 52.42%, respectively. This result indicates that cv. BRS Yellow Giant with 4 carpels generates heavier fruits, pulp and seeds with a more spherical shape.


O carpelo é a estrutura reprodutiva feminina composta por um conjunto de estigma, estilete e ovário. Normalmente as flores de maracujá possuem três carpelos, porém, algumas flores de algumas cultivares apresentam essa estrutura em maior quantidade. Neste trabalho, objetivou-se identificar relações entre o número de carpelos e as características físicas dos frutos da cultivar BRS Gigante Amarelo. Flores com três e quatro carpelos foram marcadas, polinizadas e os frutos colhidos a partir destas flores foram analisados quanto ao diâmetro transversal, diâmetro longitudinal, espessura do pericarpo, massa do fruto, massa da polpa, rendimento de polpa, número e massa das sementes. Foi utilizado o delineamento inteiramente casualizado com 10 repetições por tratamento sendo cada parcela a média de 3 frutos. Os dados foram submetidos a análises de variância e as médias foram comparadas pelo teste de Tukey a 5% de probabilidade. Os frutos gerados por flores com 4 carpelos foram 18,30% mais pesados, sua polpa foi em média 20,75% mais pesada, apresentaram diâmetro transversal 7,53% superior, ao de frutos gerados por flores com 3 carpelos. O mesmo acréscimo foi identificado quanto ao número de sementes e a massa das sementes por fruto que aumentaram 18,85% e 52,42%, respectivamente. Este resultado indica que flores da cv. BRS Gigante Amarelo com 4 carpelos geram frutos, polpa e sementes mais pesados com formato mais arredondado.

ABSTRACT

The aim of this research was to characterize a fermented yogurt-type milk drink that was elaborated from whey with the addition of aloe vera crystals and granadilla (Passiflora ligularis Juss). Four formulations for characterization were obtained: F1 (control), F2 (5% aloe vera and 15% granadilla), F3 (10% aloe vera and 10% granadilla) and F4 (15% aloe vera and 5% granadilla). Next, a sensory evaluation through a hedonic test was conducted to choose the formulation with the highest acceptance. After the best formulation was chosen, a bromatological and syneresis characterization was performed. The F4 sample had the best results in the sensory evaluation. Compared to the F1 sample, statistically significant differences (p<0.05) in all parameters except in total carbohydrates was observed for the bromatological analysis. In the percentage of syneresis, at the end of the 15 days, F4 presented a lower value in this parameter with respect to the control sample. It could be determined that the higher percentage of aloe vera and the lower percentage of granadilla had a big influence on the parameters evaluated, where it presented the best results compared to the other samples evaluated.

ABSTRACT

Yield and longevity of yellow passion fruit have been reduced by diseases such as the bacterial spot caused by Xanthomonas axonopodis pv. passiflorae. Genetic resistance has been confirmed as the most efficient and economical correct option to minimize this disease problem. Aiming at it, the objective of this research was to evaluate the incidence, severity and progression of the disease in 12 genotypes of sour passion fruit, in seedling stage in nursery greenhouse after inoculation of Xanthomonas axonopodis pv. passiflorae. The inoculation was performed with an isolate collected in the Pipiripau Rural Nucleus, Brasilia-DF, named UnB-1397 (1x106 CFU/mL), through induction of injuries. There were performed four assessments, with interval of 7 days except the first which was performed 11 days after inoculation. The incidence was estimated by the percentage of plants affected. To evaluate the severity, it was used the diagrammatic scale validated by Costa et al. (2018), with adaptations, using the measurement of the affected area by necrotic lesions on the leaf. All genotypes were susceptible to bacteriosis, 5 being considered moderately susceptible: F1BRS Pérola do Cerrado x Rosa Intenso, Mar20#21, Mar20#15b, Mar20#24xMar20#40 and FB200PL4R2 x Mar20#2005, with a mean of severity ranging from 11 to 25% of injured area in leaves.


A produtividade e a longevidade dos pomares de maracujazeiro-azedo têm sido comprometidas em razão de doenças como a bacteriose, causada por Xanthomonas axonopodis pv. passiflorae. A resistência genética tem se confirmado como a opção mais eficiente e econômica para minimizar tal problema. Dessa forma, o objetivo deste trabalho foi avaliar a reação de 12 genótipos de maracujazeiro, em fase de mudas, sob cultivo protegido, à Xanthomonas axonopodis pv. passiflorae. A inoculação com isolado denominado UnB-1397 (1x106 CFU/mL),coletado no Núcleo Rural de Pipiripau, Brasília-DF, se deu pela indução de ferimentos. Foram realizadas 4 avaliações, com intervalo de 7 dias, sendo a primeira avaliação realizada 11 dias após a inoculação. A incidência foi estimada pela porcentagem de plantas afetadas. Para avaliação da severidade, foi utilizada escala diagramática validada por Costa et al. (2018), com adaptações, utilizando-se a mensuração da área foliar atingida por lesões nas folhas. Todos os genótipos se mostraram suscetíveis à bacteriose, sendo 5 considerados moderadamente suscetíveis: F1 BRS Pérola do Cerrado x Rosa Intenso, Mar20#21, Mar20#15b, Mar20#24 x Mar20#40 e FB200PL4R2 x Mar20#2005, apresentando uma média de severidade que variou de 11 a 25% de área ou tecidos foliares lesionados.

ABSTRACT

The production of grafted passion fruit is an alternative for plant adaptation to saline environments. The objective of this study was to evaluate the effect of salt stress on physiology, biometry and fruit quality of P. edulis grafted on Passiflora spp. The experiment was conducted in completely randomized design, in a 3 x 2 factorial scheme, corresponding to three species of Passiflora (P. edulis, P. gibertii and P. cincinnata) with P. edulis scion and two levels of irrigation water salinity (0.5 - control and 4.5 dS m-1), with four repetitions. Water salinity compromises gas exchanges (CO2 assimilation raste and transpiration) and physiological variables (total chlorophyll and total water consumption) in grafted P. edulis. The interaction between the factors (water salinity x species) compromised only the growth in plant height and number of leaves. In relation to the species, auto-grafted P. edulis stood out from the other species, with higher internal CO2 concentration, number of leaves, stem dry mass, peel thickness, total soluble solids (TSS) of the pulp and TSS/TA ratio (titratable acidity). Auto-grafted P. edulis under saline conditions develops vital mechanisms (TSS and TSS/TA), which attenuates the effects of salt stress on the physico-chemical quality of the fruits.


A produção de maracujazeiro enxertado é uma alternativa para adaptação das plantas a ambientes salinos. Objetivou-se avaliar o efeito do estresse salino na fisiologia, biometria e qualidade de frutos de P. edulis enxertado em espécies de Passiflora spp. O delineamento utilizado foi inteiramente casualizado, em esquema fatorial 3 x 2, sendo três espécies de Passiflora (P. edulis, P. gibertii e P. cincinnata) tendo como copa P. edulis e dois níveis de salinidade de água de irrigação (0,5 ­ testemunha e 4,5 dS m-1), com quatro repetições. A salinidade da água compromete as trocas gasosas (taxa de assimilação de CO2 e transpiração) e variáveis fisiológicas (clorofila total e consumo hídrico total) em P. edulis enxertado. A interação entre os fatores (salinidade da água x espécie) compromete apenas o crescimento em altura de plantas e número de folhas. Em relação às espécies, o P. edulis auto enxertado se destaca em relação as demais espécies apresentando maior concentração interna de CO2, número de folhas, massa seca de caule, espessura da casca do fruto, sólidos solúveis totais (SST) da polpa e razão sólidos solúveis totais por acidez titulável (SST/AT). O P. edulis auto enxertado sob condições de salinidade, desenvolve mecanismos vitais (SST e SST/AT), que atenuam os efeitos do estresse salino na qualidade físico-química dos frutos.

ABSTRACT

CABMV is a limiting virus for passion fruit crop in Brazil, its main producing country. This virus has been reported in all producing states of the country, with the state of Santa Catarina (SC) in 2017 standing as the third largest passion fruit producer. In 2017, it reached 8.4% of the national production. The southern coast is the main responsible for the increase in production, which has been supplying the domestic market. However, in that same year, this region recorded the first symptom expressions in plants and fruits. The evaluation of the samples collected in the municipalities of Sombrio, Praia Grande and São João do Sul, southern coast of SC, was performed by using a mechanical transmission to indicator plants, PTA-ELISA and RT-PCR, and by sequencing. The evaluation results were positive for CABMV and negative for CMV in PTA-ELISA. In RT-PCR, there was the formation of a 700bp ca band, expected size for Potyvirus, whose sequence comparison with those deposited in GenBank reveled 98% identity with the isolates from São Paulo State. The occurrence of the virus in the southern coast of SC did not reach a serious decrease in passion fruit production due to the union of producers, who adopted preventive management measures to control the virus, whose effect led to a consolidation of the passion fruit production chain in the region.(AU)


O CABMV é um vírus limitante para a cultura do maracujá no Brasil, principal país produtor mundial, cuja ocorrência já foi relatada em todos os estados produtores. Em 2017, o estado de Santa Catarina (SC) foi o terceiro maior produtor de maracujá no Brasil, responsável por 8,4% da produção nacional, sendo o litoral sul o principal responsável pelo aumento da produção, garantindo o abastecimento do mercado interno. Entretanto, nesse mesmo ano, essa região registrou as primeiras expressões de sintomas em plantas e frutos. Uma avaliação das amostras coletadas nos municípios de Sombrio, Praia Grande e São João do Sul, litoral sul de Santa Catarina, foi realizada por transmissão mecânica para plantas indicadoras, PTA-ELISA, RT-PCR e sequenciamento. Os resultados foram positivos para o CABMV e negativos para o CMV, tanto em PTA-ELISA quanto RT-PCR. Na RT-PCR, houve a amplificação de bandas com ca de 700pb, tamanho esperado para o Potyvirus cuja comparação de sequências com as depositadas no GenBank revelaram 98% de similaridade com os isolados do estado de São Paulo. A ocorrência do vírus na região do litoral sul de Santa Catarina não causou quebra na produção de maracujá devido à adoção conjunta de medidas preventivas de manejo pelos produtores, fato que consolidou a cadeia produtiva do maracujá na região.(AU)

ABSTRACT

O maracujá (Passiflora ssp.) é conhecido por suas características sensoriais e por apresentar diversos compostos bioativos. Estudos prévios demonstraram que o consumo a longo prazo de maracujá melhorou os parâmetros bioquímicos, inflamatórios e antioxidantes. Uma espécie que tem despertado interesse é a Passiflora tenuifila Killip consumida pela população local, porém, ainda com baixa expressão comercial. Assim, o objetivo deste trabalho consiste em avaliar o efeito da ingestão a médio prazo de maracujá (P. tenuifila Killip) em indivíduos eutróficos e obesos. Inicialmente foi realizada uma caracterização do fruto em dois estágios de amadurecimento (verde e maduro), uma vez que são consumidas nestas duas formas. Foram avaliadas características físicoquímicas e o perfil de flavonoides por HPLC-ESI-MS/MS. O conteúdo de Sólidos Totais Solúveis variou entre 20,80 e 23,55° Brix, porém não foi observada diferença significativa entre os dois estágios. Os principais açúcares identificados foram a sacarose e glicose, variando entre 4,0-8,5%, apresentando maior conteúdo no estádio verde (p<0.05). Os principais ácidos orgânicos encontrados foram o cítrico, tartárico e málico, no entanto os teores variaram entre os lotes analisados. Os frutos nos dois estádios apresentaram o mesmo perfil de flavonoides, apresentando como compostos majoritários a procianidinaTipo B e flavonas C -glicosiladas (luteolina e apigenina). Após a caracterização do fruto, foram recrutados indivíduos adultos (entre 19 e 59 anos), eutróficos (IMC= 19,0- 24,99 Kg/m2) ou obesos (IMC > 30,00) que ingeriram durante 30 dias uma dose diária do maracujá (P. tenuifila Killip). Foram avaliados marcadores antropométricos, perfil bioquímico sérico, do estresse oxidativo e permeabilidade intestinal. Foi avaliado também a excreção de flavonoides na urina por HPLC-ESI-QTOF-MS/MS e a microbiota intestinal por 16s rRNA. A ingestão diária por somente 30 dias de uma porção de P. tenuifila Killip demonstrou grandes benefícios. O consumo da P. tenuifila Killip foi responsável pela redução da concentração de colesterol total e LDL sérico dos indivíduos obesos (p<0,05). Foi observado tendência na redução da permeabilidade intestinal e redução significativa (p<0,05) no biomarcador do estresse oxidativo 8-OHdG (associado à dano à estrutura do DNA). O consumo do maracujá P. tenuifila Killip aumentou a excreção de metabólitos na urina produzidos a partir da metabolização de flavonas-C-glicosiladas e flavan-3-ol e, por fim, foi capaz de modular a microbiota reduzindo a abundância relativa do filo Firmicutes (associada a obesidade) e aumentando a proporção de Lachonospiraceae (família associada à redução de inflamação local e ao metabolismo de compostos fenólicos)


Passion fruit (Passiflora ssp.) is known for its sensory characteristics and for presenting various bioactive compounds. Previous studies shown that long-term passion fruit consumption has improved biochemical, inflammatory and antioxidant parameters. A species that has aroused interest is Passiflora tenuifila Killip consumed by the local population, but has no commercial expression yet. The objective of this study is to evaluate the effect of medium-term intake of passion fruit (P. tenuifila Killip) on eutrophic and obese subjects. Initially, the fruit was characterized in two ripening stages (green and ripe), which are the most consumed stages. Physico-chemical characteristics and flavonoid profile were evaluated by HPLC-ESI-MS/MS. The total soluble solids content ranged from 20.80 to 23.55 ° Brix, but no significant difference was observed between the two stages. The main sugars identified were sucrose and glucose, ranging from 4.0- 8.5%, with higher content in the green stage (p<0.05). The main organic acids found were citric, tartaric and malic, however the levels varied between the lots analyzed. The fruits in both stages presented the same profile of flavonoids, presenting as major compounds procianidin Type B and C-glycosylated flavones (luteolin and apigenin). After fruit characterization, adult (between 19 and 59 years), eutrophic (BMI = 19.0-24.99 Kg/m2) or obese (BMI>30.00) ingested for 30 days a daily dose of passion fruit (P. tenuifila Killip) and anthropometrics indicators, serum biochemical profile, oxidative stress and intestinal permeability were evaluated. The excretion of flavonoids in urine by HPLC-ESI-QTOF-MS/MS and intestinal microbiota by 16s rRNA was also evaluated. Daily intake for only 30 days of a portion of P. tenuifila Killip has shown great benefits. The P. tenuifila Killip consumption was responsible for reduction of total cholesterol and LDL in obese subjects (p<0.05). There was a tendency to reduce intestinal permeability and a significant reduction (p<0.05) of 8-OHdG (oxidative stress biomarker, associated with damage to DNA structure). P. tenuifila Killip consumption increased the excretion of urine metabolites produced by metabolization of flavones-C-glycosylated and flavan-3-ol and, finally, was able to modulate the microbiota, reducing the relative abundance of the Firmicutes (phylum associated with obesity) and increasing the proportion of Lachonospiraceae (family associated with reduced local inflammation and metabolism of phenolic compounds)

ABSTRACT

Background: Passiflora quadrangularis L. has antihypertensive and anxiolytic properties observed in experimental models. Objectives: The aim of this work was to establish the vascular effects exerted by two known monodesmosidic triterpene saponins, 3-O-ß-D-glucopyranosyloleanolic acid (Compound 1) (not previously described for this plant) and, 3-O-[ß-D-glucopyranosyl-(1→2)-ß-D-glucopyranosyl] oleanolic acid (Compound 2), isolated from the ethanolic extract of Passiflora quadrangularis L. leaves. Methods: The structural elucidation was achieved by Nuclear Magnetic Resonance (NMR) experiments and High-Resolution Mass Spectrometry (HRMS). Aortic rings from Wistar rats, previously stimulated with phenylephrine (PE, 1µM) and washed, were exposed to cumulatively concentrations of compound 1 and compound 2 (10 to 400 µM). Ethanolic extract from leaves of P. quadrangularis L. (10 to 320 µg/ mL) and clonidine (1nM to 100µM) were also used for comparison. Concentration response curves of compounds 1 and 2 were examined in presence and absence of: endothelium, the alpha-2 antagonist yohimbine (1 and 100 µM), the alpha non selective antagonist phentolamine (1µM), the alpha-1 antagonist prazosin (1µM) and the calcium channel blocker verapamil (10 and 100 µM). In addition, cumulatively response curve of acetylcholine (ACh, 10nM to 10µM) and sodium nitroprusside (SNP, 1nM to 100µM) were assayed in rings precontracted with compounds 1 and 2 (400 µM). Results: Compounds 1 and 2 elicited a vasoconstriction response in intact aorta rings in similar way (pEC50: 3.92±0.01 and 4.09±0.01, respectively), effect that did not change in denuded rings (pEC50: 3.90±0.01 and 4.11±0.01). The potency order (pEC50) of compounds 1 and 2 decreased according to the following: verapamil (3.53±0.01 and 3.90±0.02; p<0.05) < yohimbine (3.65±0.01 and 3.94±0.02; p<0.05) < prazosin (3.86±0.01 and 4.30±0.02) < phentolamine (4.05±0.02 and 4.05±0.01). SNP but not ACh, was able to decrease the vasopressor effect of compounds 1 and 2 (pIC50: 8.61±0.01 and 8.24 ± 0.15, respectively). Conclusions: Compounds 1 and 2 are key metabolites responsible for the ex vivo vasoconstrictor response induced by P. quadrangularis L. Activation of voltage-dependent calcium channels and/or α2-adrenergic receptors stimulation could be mechanisms implicated.


Antecedentes: Passiflora quadrangularis L. tiene propiedades antihipertensivas y ansiolíticas observadas en modelos animales. Objetivos: El objetivo de este trabajo fue establecer los efectos vasculares ejercidos por dos conocidas saponinas triterpénicas monodesmosídicas: el ácido 3-O-ß-D glucopiranosiloleanólico (Compuesto 1) (no descrito previamente para esta especie vegetal) y el ácido 3-O-[ß-D-glucopiranosil- (1→2)-ß-D-glucopiranosil]oleanólico (Compuesto 2), aisladas del extracto etanólico de las hojas de Passiflora quadrangularis L. Métodos: La elucidación estructural se llevó a cabo mediante experimentos de Resonancia Magnética Nuclear (NMR) y determinaciones de Espectrometría de Masas de Alta Resolución (HRMS). Los anillos aórticos de ratas Wistar, previamente estimulados con fenilefrina (PE, 1 µM) y lavados, fueron expuestos a concentraciones acumulativas del compuesto 1 y compuesto 2 (10 a 400 µM). El extracto etanólico de las hojas de P. quadrangularis L. (10 a 320 µg / ml) y clonidina (1 nM a 100 µM) se utilizaron para la comparación. Las curvas de concentración respuesta de los compuestos 1 y 2 se examinaron en presencia y ausencia de: endotelio, el antagonista alfa-2 yohimbina (1 y 100 µM), el antagonista alfa no selectivo fentolamina (1 µM), el antagonista alfa-1 prazosina (1 µM) y el bloqueador de canales de calcio verapamilo (10 y 100 µM). Además, la curva de concentraciones acumulativas de acetilcolina (ACh, 10 nM a 10 µM) y nitroprusiato de sodio (SNP, 1 nM a 100 µM) se ensayó en anillos pre-contraídos con los compuestos 1 y 2 (400 µM). Resultados: Los compuestos 1 y 2 provocaron una respuesta de vasoconstricción en los anillos de aorta intactos de manera similar (pEC50: 3.92 ± 0.01 y 4.09 ± 0.01, respectivamente), este efecto no cambió en los anillos denudados (pEC50: 3.90 ± 0.01 y 4.11 ± 0.01). El orden de potencia (pEC50) de los compuestos 1 y 2 disminuyó de la siguiente manera: verapamilo (3.53 ± 0.01 y 3.90 ± 0.02; p <0.05) < yohimbina (3.65 ± 0.01 y 3.94 ± 0.02; p <0.05) < prazosina (3.86 ± 0.01 y 4.30 ± 0.02)

ABSTRACT

Objetivou-se avaliar o consumo, a digestibilidade e o desempenho de ovinos, arraçoados com dietas isoproteicas, contendo 75% de resíduos da agroindústria frutífera (abacaxi, acerola, maracujá e cupuaçu), uma dieta com feno de tifton e 25% de concentrado, em delineamento inteiramente ao acaso. A participação do resíduo de maracujá na dieta proporcionou os maiores níveis de consumo de matéria seca (1170,6g d-1) em relação aos resíduos de abacaxi (693,8g d-1), acerola (644,2g d-1), cupuaçu (452,9g d-1) e feno de tifton (962,7g d-1), o que se relaciona aos seus níveis de digestibilidade (77,8; 63,1; 59,1; 61,7 e 71,8%, respectivamente). Tal resultado gerou diferenças significativas, destacando-se o resíduo de maracujá quanto à conversão alimentar (8,3), e o ganho médio diário de peso (141,5g d-1). Apesar de ter tido a mesma conversão observada para o feno de tifton (13,2), apresentou maior ganho médio diário (75,6g d-1). Os demais resíduos apresentaram efeitos sobrepostos, contudo o resíduo de acerola ficou com a pior conversão (51,4) e o menor ganho médio diário (15,6g d-1), sendo esse sem diferença em relação ao cupuaçu (23,0g d-1). Os resíduos podem ser utilizados como alternativa para a alimentação de ovinos.(AU)


The objective was to evaluate the consumption, digestibility and performance of the sheep with iso protein diets, with 75% of residues from fruit agro-industries (pineapple, acerola, passion fruit, and cupuassu) and a diet with tifton hay, and 25% of concentrate, in a totally randomized design. The participation of passion fruit residue on the diet provided the highest consumption levels of dry matter (1170.6g d -1 ) compared with the residues of pineapple (693.8g d -1 ), acerola (644.2g d -1 ), cupuassu (452.9g d -1 ) and tifton hay (962.7g d -1 ), which is related to their levels of digestibility (77.85, 63.14, 59.07, 61.68 and 71.83%, respectively). Such a result generated significant differences with emphasis on passion fruit residue regarding food inversion (8.30) and average daily weight gain (141.50g d -1 ), in spite of having the same conversion detected for tifton hay (13.2), it showed a higher average daily gain (75.6g d -1 ). The other residues showed overlapping effects, however, acerola residue showed the worst conversion level (51.4) and the lowest average daily gain (15.6g d -1 ), and this one showed no difference compared with cupuassu (23.0g d -1 ). The residues can be used as an alternative for sheep feeding.(AU)

ABSTRACT

Bacterial spot (Xanthomonas axonopodis pv. passiflorae) significantly reduces yellow passion fruit (Passiflora edulis Sims) yield and longevity. A standard area diagram set (SADs) for severity assessment of bacterial spot on tri-lobed leaves of yellow passion was developed and validated in this study. The SADs consisted of eight severity levels (2; 4; 9; 18; 35; 58; 80; and 94%). For its validation, 20 raters, who initially estimated the disease severity without the aid of the SADs, were divided into four groups (G1 and G3, inexperienced; G2 and G4, experienced). Subsequently, G1 and G2 performed the second evaluation without the SADs, and G3 and G4 completed the second evaluation with the proposed SADs. The accuracy and precision of the assessments were determined by simple linear regression and by the Lin's concordance correlation coefficient (LCCC). The proposed SADs allowed accurate and precise quantification of bacterial spot severity, increasing the agreement between estimated and actual values. Inexperienced raters benefited the most from the use of the SADs. The increase in accuracy and precision in the non-aided groups, when present, was less pronounced than those increments observed in the SADs-aided groups. The LCCC confirmed the increases in accuracy and precision detected by the linear regression analysis.


A bacteriose (Xanthomonas axonopodis pv. passiflorae) reduz significativamente a produção e longevidade do maracujazeiro azedo (Passiflora edulis Sims). Uma escala diagramática para a avaliação da severidade da bacteriose em folhas trilobadas do maracujazeiro azedo foi desenvolvida e validada neste estudo. A escala diagramática apresentou oito níveis de severidade (2; 4; 9; 18; 35; 58; 80 e 94%). Para a sua validação, os 20 avaliadores foram divididos em quatro grupos (G1 e G3, sem experiência; G2 e G4, com experiência), que inicialmente estimaram a severidade da doença sem auxílio da escala. Posteriormente, G1 e G2 fizeram outra avaliação sem escala, e G3 e G4 realizaram a avaliação com a escala proposta. A acurácia e a precisão das estimativas foram determinadas por regressão linear simples e pelo coeficiente de correlação de concordância de Lin (LCCC). A escala diagramática proposta permitiu quantificar a severidade da bacteriose de forma acurada e precisa, aumentando a concordância entre os valores estimados e os reais. Os avaliadores inexperientes foram os mais beneficiados pelo uso da escala. O aumento da acurácia e precisão nos grupos que realizaram dupla avaliação sem escala, quando ocorreu, foi mais discreto que os incrementos observados nos grupos que utilizaram a escala. O LCCC confirmou os incrementos da acurácia e precisão detectados pela análise de regressão linear.

ABSTRACT

Brazil is the largest producer of yellow passionfruit (Passiflora edulis f. flavicarpa) and one of its production problems is the anthracnose (Colletotrichum spp.). The use of fungicides on control of postharvest diseases is a method that protects the fruits during storage. However, precautions must be taken due to fungicide toxicity. The restriction to the use of fungicides in post-harvest led a demand for alternative methods of disease control, and, the phosphite application is one of these methods. Therefore, this work aimed to evaluate the effects of fruit immersion in phosphite on postharvest control of anthracnose. Two tests were developed in vitro to assess the effect on the fungus: phosphite Mg2 (40%P2O5+6%Mg), Zn (40%P2O5+10%Zn), Ca1 (30%P2O5+7%Ca) and K1 (40%P2O5+20%K2O). For the in vivo tests, passionfruit (Gigante Amarelo), were wounded and inoculated (50L; 106conidia mL-1). Two tests were done with: Cu (25%P2O5+5%Cu), 2.5mL L-1; Zn, 2.5mL L-1; K1, 2.5mL L-1; Mg1 (30%P2O5+4%Mg), 3mL L-1; Ca1, 3mL L-1; Ca2 (10%P2O5+6%Ca), 4mL L-1; K2 (40%P2O5+20%K2O), 1.5mL L-1; Mg2 (40%P2O5+6%Mg), 1.5mL L-1; K3 (20%P2O5+20%K2O) 1.75 mL L-1; K4 (30%P2O5+20%K2O), 1.75mL L-1. Other two tests with phosphites Mg2, Ca1, Zn and K1 were with CaCl2 (2%) was developed. In addition, phosphites were tested at 25, 50, 100 and 200% of the dose: K2 (100%; 1.5mL L-1) and Ca1 (100%; 3 mL L-1). The phosphites Mg2, Ca1, K1 and Zn in vitro have reduced mycelial growth and fungus conidia production. The phosphites K1, K2, Ca1 and Zn were the ones that most reduced the size of the anthracnose lesion. There were no differences among treatments, concerning the physico-chemical fruit properties analyzed (% fresh mass loss, total soluble solids, pH and titratable acidity).


O Brasil é o maior produtor mundial de maracujá-amarelo (Passiflora edulis f. flavicarpa) e um dos problemas para sua produção é a antracnose (Colletotrichum spp.). O uso de fungicidas no controle de doenças pós-colheita é um método que protege os frutos durante o armazenamento, mas, precauções adicionais devem ser tomadas quanto à sua toxidade, presença de resíduos e a provável seleção de fungos resistentes. A restrição ao uso de fungicidas na pós-colheita cresceu e levou à procura de alternativas de controle, e, entre tais está à aplicação de fosfitos. Diante disso, este trabalho objetivou avaliar os efeitos da imersão de frutos em soluções de fosfitos no controle da antracnose em pós-colheita. Dois testes in vitro foram feitospara avaliar o efeito de fosfitono fungo: Mg2 (40%P2O5+6%Mg), Zn (40%P2O5+10%Zn), Ca1 (30%P2O5+7%Ca) e K1 (40%P2O5+20%K2O). In vivo, frutos de maracujá (Gigante Amarelo), foram feridos e inoculados (50l; 106conídios mL-1). Dois testes foram feitos com: Cu (25%P2O5+5%Cu), 2,5mL L-1; Zn, 2,5mL L-1; K1, 2,5mL L-1; Mg1 (30%P2O5+4%Mg), 3mL L-1; Ca1, 3mL L-1; Ca2 (10%P2O5+6%Ca), 4mL L-1; K2 (40%P2O5+20%K2O), 1,5mL L-1; Mg2 (40%P2O5+6%Mg), 1,5mL L-1; K3 (20%P2O5+20%K2O), 1,75mL L-1; K4 (30%P2O5+20%K2O), 1,75mL L-1. Outros dois testes com fosfitos foram com CaCl2 (2%) e Mg2, Ca1, Zn e K1. Ainda, dois fosfitos foram testados a 25, 50, 100 e 200% da dose: K2 (100%; 1,5mL L-1) e Ca1 (100%; 3mL L-1). Os fosfitos Mg2, Ca1, K1 e Zn in vitro reduziram o crescimento micelial e a produção de conídios do fungo. Os fosfitos K1, K2, Ca1 e Zn foram que mais reduziram o diâmetro da lesão causada pelo patógeno. Ca1 e K1 com CaCl2 reduziram o tamanho das lesões. Não houve diferenças significativas entre os tratamentos, quanto as características físico-químicas analisadas (% perda de massa fresca, teor de sólidos solúveis totais, pH e acidez titulável) dos frutos.

ABSTRACT

Abstract Passion fruits species presents a larger economic importance for in natura consumption and industry. The main way to propagate these species is by seeds; however, the aril presence and environmental conditions may inhibit the seeds germination. In this sense, the objective of this study was to evaluate the effect of aril removal methods and light conditions on P. edulis var. flavicarpa seeds quality and germination. There were used five methods to remove the seeds aril: (1) friction on steel mesh sieve for 5 minutes; (2) friction with coarse sand on steel mesh sieve for 5 minutes; (3) immersion in lime solution at 10% (w/v), for 30 minutes; (4) fermentation in sugar solution at 10% (w/v), during 48 hours; and (5) natural pulp fermentation, during five days. The seeds were submitted to germination test at darkness and lightness, as well as, to length seedlings and emergence test. Regardless the aril removal method, the germination percentage was lower at lightness than darkness highlighting the natural pulp fermentation treatment, which presented 86% of seeds germinated. On the other hand, the aril removal methods did not affect the seedlings emergence, with emergence percentages ranged from 88 to 94%.


Resumo As espécies de maracujá apresentam grande importância econômica, tanto para o consumo in natura, quanto para a indústria. A principal maneira de propagar essas espécies é por sementes; contudo, a presença de arilo e condições ambientais pode inibir a germinação. Nesse sentido, objetivou-se estudar o efeito de métodos de remoção do arilo e luminosidade na qualidade e germinação das sementes de Passiflora edulis var. flavicarpa. Cinco métodos foram empregados para a remoção do arilo: (1) fricção em peneira de malha de aço por cinco minutos; (2) fricção com areia grossa em peneira de malha de aço por cinco minutos; (3) imersão em solução de cal a 10% (m/v), por 30 minutos; (4) fermentação da polpa em solução de açúcar a 10% (m/v), por 48 horas; e (5) fermentação natural da polpa, por cinco dias. As sementes foram submetidas ao teste de germinação no escuro e no claro, teste de comprimento de plântulas e teste de emergência. Independente do método de remoção do arilo, a porcentagem de germinação no claro apresentou-se menor em comparação ao escuro, com destaque para o tratamento de fermentação natural da polpa, o qual apresentou 86% de sementes germinadas. Por outro lado, os métodos de remoção do arilo não afetaram a emergência das plântulas, com porcentagem de emergência variando entre 88 a 94%.

ABSTRACT

The Lonchaeidae family comprises species that are considered of major economic importance due of their damage in several crops. In sweet passion fruit (Passiflora ligularis Juss), these flies cause high infestation in flower buds and fruits, however only a few basic studies about the species associated with the damage are available. Samples of flower buds and fruits were taken and McPhail trap baits with Torula yeast were placed in sweet passion fruit orchards in Oxapampa (Pasco, Peru) in 2015­2016. In addition, other hosts were collected in this period. We found Dasiops inedulis Steykal infesting the flower buds, while Dasiops frieseni Norrbom & McAlpine infesting sweet passion fruits. Moreover, other Lonchaeidae-hosts interactions are related. Through Torula yeast baits, 14 species of lance flies were detected and high numbers of D. inedulis specimens were captured.(AU)


A família Lonchaeidae inclui espécies que são consideradas de grande importância econômica devido aos seus danos em diferentes cultivos. No maracujá-doce (Passiflora ligularis Juss), essas moscas causam altas infestações em botões florais e frutos, tendo ainda poucos estudos sobre as espécies associadas aos danos. Amostragem de botões florais e frutos foram realizadas e armadilhas McPhail com levedura de Torula foram colocadas em fazendas de maracujá em Oxapampa (Pasco, Peru) durante os anos de 2015 e 2016. Além disso, outros hospedeiros foram coletados nesse período. Nós encontramos Dasiops inedulis Steykal infestando botões florais e Dasiops frieseni Norrbom & McAlpine em frutos de maracujá-doce. Além disso, outras interações Lonchaeidae-hospedeiro são relacionadas. Mediante iscas de levedura de Torula, 14 espécies de Lonchaeidae foram detectadas e altos números de espécimes de D. inedulis foram capturados.(AU)

ABSTRACT

Soluble epoxide hydrolases (sEH) are enzymes present in all living organisms, metabolize epoxy fatty acids to 1,2-diols. sEH in the metabolism of polyunsaturated fatty acids plays a key role in inflammation. In addition, the endogenous lipid mediators in cardiovascular disease are also broken down to diols by the action of sEH that enhanced cardiovascular protection. In this study, sEH inhibitory guided fractionation led to the isolation of five phenolic compounds trans-resveratrol (1), trans-piceatannol (2), sulfuretin (3), (+)-balanophonin (4), and cassigarol E (5) from the ethanol extract of the seeds of Passiflora edulis Sims cultivated in Vietnam. The chemical structures of isolated compounds were determined by the interpretation of NMR spectral data, mass spectra, and comparison with data from the literature. The soluble epoxide hydrolase (sEH) inhibitory activity of isolated compounds was evaluated. Among them, trans-piceatannol (2) showed the most potent inhibitory activity on sEH with an IC₅₀ value of 3.4 µM. This study marks the first time that sulfuretin (3) was isolated from Passiflora edulis as well as (+)-balanophonin (4), and cassigarol E (5) were isolated from Passiflora genus.

ABSTRACT

Although the number of prescriptions and dependence on sleeping pills are increasing, the associations with unexpected abnormal behaviors and metabolic diseases caused by the overuse of sleeping pills are not well understood. In particular, such as abnormal eating-behavior and the occurrence of metabolic disorders caused by psychological unstable states are reported. For this reason, herbal medicine, which has not had such side effects in recent years, is attracting attention as an alternative medicine/food for sleeping inducer. We have used ethanol extracts from Passiflora incarnata (PI) to steadily obtain positive effects on sleep and brain microenvironment. However, as mentioned earlier, sleep-inducing efficacy can only be used safely if the behavioral and metabolic abnormalities do not appear.Thus, in this study, we used Phenomaster equipment to continuously monitor the movement, feeding, water consumption, gas changes, etc. in C57BL/6 mice at a dose of 500 mg/kg/day for 5 consecutive days with PI extract group compared with the control group. Before sacrifice, differences in body composition of mice were also compared. Monitoring of 24 h/5 days through the equipment showed no change in PI-treated group in anything except for significant decrease in blood melatonin levels and activity after PI administration. Taken together, the statistically insignificance of any behavioral and metabolic phenomenon produced by repeated treatment of PI are not only expected to have an accurate sleep effect, but are also free of side effects of the prescribed sleeping pills. This study has given us greater confidence in the safety of the PI extracts we use for sleep-inducer.

ABSTRACT

ABSTRACT The present study reports a shoot organogenesis-based system for in vitro regeneration of Passiflora miniata, an Amazonia passion fruit species. Root segments were cultured in Murashige and Skoog (MS) medium supplemented with different concentrations (range 2-9 µM) of 6-benzyladenine (BA); thidiazuron (TDZ) or kinetin (KIN). Plant growth regulators were not added to the control treatment. Root explants have showed a high regenerative potential. After 30 days of in vitro culture, the root explants showed several shoots formed direct and indirectly. TDZ provided the best response in the differentiation adventitious shoots, mainly in the presence of 6.8 µM. The cytokinins BA and KIN responded producing a reduced number of shoots. After 120 days, rooted regenerated plants were transferred to a greenhouse for acclimatization. This regeneration system opens new perspectives for micropropagation and conservation of this wild Amazonic passion fruit species.
