RESUMO
Framboesa é uma pequena fruta de grande importância econômica, que contém numerosos compostos fenólicos, com potenciais benéficos à saúde, porém, quando cultivada em regiões subtropicais possui baixa produtividade. Objetivou-se, neste trabalho, avaliar a produtividade de framboeseiras 'Batum', produzidas com ou sem cobertura plástica sobre o dossel das plantas, em duas densidades de plantio, sendo 0,25m e 0,5m entre plantas e 3,0m entre linhas e avaliadas por dois ciclos de produção (2012/13 e 2013/14), em região subtropical. O delineamento experimental adotado foi em blocos ao acaso, em esquema fatorial 2x2x2, com 6 blocos e 10 plantas por parcela. Foram avaliadas as características produtivas como número de frutos por planta, produção por planta e produtividade estimada. Além disso, foram demarcados os índices fenológicos, análises vegetativas e fisiológicas. O menor espaçamento de plantio entre as plantas (0,25m) e o plantio sem cobertura plástica sobre o dossel das plantas resultaram em maior produtividade das framboseiras 'Batum'.
Raspberry is an economically important berry crop, its fruit contains numerous phenolic compounds with potential health benefits, however ver, in subtropical areas has been low production. The objective of this study was to evaluate the productivity of raspberry 'Batum' produced with or without plastic cover over the plant canopy and two planting densities, being 0.25m and 0.5m between plants and 3.0m between rows and cycles (2012/13 and 2013/14), in subtropical area. The experimental design was randomized blocks, factorial 2x2x2 with 6 blocks and 10 plants per plot. It was evaluated the productive plant characteristics such as number of fruits per plant, production per plant and productivity estimated. Moreover,phenological data, vegetative and physiologic analysis. The planting densities at 0.25m between plants and without plastic cover over the plant canopy result in increased productivity of raspberry 'Batum'.
RESUMO
The objective of this research was to verify the potential rhizogenic stem cuttings and root of raspberry (Rubus idaeus L.). Cuttings of 'Batum' cultivar was stored cold (4°C) for 10, 20 and 30 days, and a control without storage. Subsequently, the cuttings were treated with indolebutyric acid (IBA) at 0, 1000, 2000, 3000 and 4000mg L-1 and root cuttings with benzylaminopurine (BAP) at 0, 300, 600, 900, 1200 and 1500mg L-1 by 10 seconds. The cuttings were buried in 2/3 of its length in the vertical position, and root was completely buried in the horizontal position at three inches deep. It was used vermiculite medium as substrate, and these experiments were conducted in a greenhouse with 50% shading. Evaluations were made 75 days after planting the cuttings. It was concluded that the use of cuttings is not feasible and that the root cuttings need not be stimulated by cold storage or treatment with BAP.
O objetivo deste trabalho foi verificar o potencial rizogênico de estacas caulinares e radiculares da framboeseira (Rubus idaeus L.). Estacas da cultivar 'Batum' foram armazenadas a frio (4ºC) por 10, 20 e 30 dias, além do controle sem armazenamento. Posteriormente, as estacas caulinares foram tratadas com ácido indolilbutírico (AIB) a 0, 1000, 2000, 3000 e 4000mg L-1 e as estacas radiculares com benzilaminopurina (BAP) a 0, 300, 600, 900, 1200 e 1500mg L-1 por 10s. As estacas caulinares foram enterradas em 2/3 de seu comprimento, na posição vertical e as radiculares foram totalmente enterradas na posição horizontal, a três centímetros de profundidade. Utilizou-se vermiculita de grânulos médios como substrato, e estes experimentos foram conduzidos sob telado com sombreamento de 50%. As avaliações foram feitas após 75 dias do plantio das estacas. Concluiu-se que o uso de estacas caulinares não é viável e que as estacas radiculares não necessitam ser estimuladas pelo armazenamento a frio ou do tratamento com BAP.
RESUMO
Object\ To establish a plantlet regeneration system of Rubus idaeus L for the purpose to obtain a large number of high quality seedling in a short time Methods\ Stem apex and part of the stem were used as the explant and the optimal culture media and conditions were selected by orthogonal design Results\ An optimum culture medium for the induction of callus, adventitious bud and root was obtained which can be carried out in the laboratory with comparative ease and good repeatability Conclusion\ A basic medium + BA 0 2 mg/L+NAA 1 0～1 5 mg/L was most suitable for the induction of callus; a medium + BA 1 mg/L+NAA 0 1～0 2 mg/L+GA 3 6～8 mg/L+CH 300 mg/L was good for the induction of bud; a medium +BA 1 mg/L+NAA 0 1 mg/L+GA 3 2 mg/L was suitable for propagation of the bud; and the basic medium+IBA 0 1 mg/L+NAA 0 5 mg/L was good for the induction of root
