RESUMO
The aim of the study is to identify the suitable modified atmospheric storage condition required for long term storage of groundnut (Arachis hypogaea L.) variety TMV (Gn) 13. The experiment was conducted during 2022 at Department of Seed Science and Technology, Tamil Nadu Agricultural University, Coimbatore. The groundnut pods and kernels were subjected into different storage conditions viz., pods stored in gunny bag, kernels stored in gunny bag, kernels stored in polythene bag, kernels stored with N?gas and kernels stored in vacuum conditions. The results revealed that pod storage recorded the maximum germination percentage (73%), root length (14.5cm), shoot length(14.3cm), dry matter production (3.47 g 10 seedlings -1) and vigour (2136). Similarly, enzymes viz., dehydrogenase( 0.72 OD value), peroxidise (1.29U mg?¹ protein min?¹), alpha amylase (13.60mg maltose min-1) and catalase activity (1.253 µmolH?O? min?¹g?¹ protein) were also maximum in pod storage with minimum harmful effect of pest(0.6%) and fungus incidence(17%). The nitrogen storage conditions also have maximum enzyme activity viz., dehydrogenase (0.64 OD value), peroxidise (1.24U mg?¹ protein min?¹), alpha amylase (13.58 mg maltose min-1) and catalase activity (1.220 µmolH?O? min?¹g?¹ protein) with minimum harmful effect of pest (0.6%) and fungus incidence (20%). Present study, it is concluded that groundnut kernels stored under modified atmospheric storage i.e. nitrogen gas storage can maintain the seed longevity by minimizing the deterioration process in groundnut equally as that of pod storage. Further, it will helps to minimize the expenditure towards transport and storage.
RESUMO
The present study was focused on the evaluation of foliar spray treatment to arrest the flower drop in order to increase the seed set and seed yield in greengram. The crop of greengram var.CO 8 was raised by adopting the recommended package of practices during rabi season during 2019 and 2020 at Department of Seed Science and Technology, TNAU, Coimbatore. Foliar application of different nutrients viz., Nutrigold 0.50%, ZnSO4 0.10%, Mono ammonium phosphate 2%, as treatments were sprayed at bud initiation (30 days after sowing) and 7 days after flowering stages. Pulse wonder @ 5 kg ha?1 was sprayed during peak flowering stage. Unsprayed plots served as control. During the investigations, data on flower production, arresting of flower drop, seed set, seed filling, seed yield and quality of greengram were recorded and studied.In the study, significant variations were observed due to the foliar applications. Days to 50 per cent flowering, number of flowers per plant, number of pods per plant, conversion efficiency percentage, pod yield ha-1and seed yield ha-1were significantly higher with foliar spray of Nutrigold 0.50% applied at bud initiation and 7 days later which was on par with Pulse wonder @ 5 kg ha?1 applied during peak flowering stage. The percentage of flower drop was less in Nutrigold 0.50%(39.69%) which was on par with Pulse wonder @ 5 kg ha?1 (41.04%) when compared to control (52.02%). Seed quality parameters such as seed recovery, 100 seed weight, seed germination and vigour of seedlings were significantly higher in foliar spray of Nutrigold 0.50% when compared to other treatments.From this study, it could be concluded that the foliar application of Nutrigold 0.50% during bud initiation and 7 days after flowering or Pulse Wonder @ 5kg/ ha during peak flowering could be effectively applied to maximize the flower production, arrest the flower drop and to improve the seed yield and quality in greengram.
RESUMO
The present study focused on the evaluation of priming with water and various botanical leaf extract and followed by humid invigoration as a means to improve seed germination and seedling vigour of ribbed gourd (COH 1) and bitter gourd (CO 1). The seeds of these gourds were primed with water and various leaf extracts at 2% concentration viz., Pongam (Pongamia pinnata L.), Neem (Azadira chtaindica), Moringa (Moringa oleifera), Curry leaf (Murraya koenigii), Notchi (Vitex negundo), Coconut (Cocos nucifera), Hena (Lawsonia inermis) and Guava (Psidium guajava). Unprimed seeds taken as a control. Hydro and leaf extract priming with humid invigoration process significantly influence the germination and seedling vigour of both crops viz., ribbed gourd (COH 1) and bitter gourd (CO 1). The study revealed that highest seed and seedling quality characters like germination percentage, speed of germination, seedling length, dry matter production, vigour index I and vigour index II were recorded in hydro primed with humid invigoration. Among the leaf extracts moringa shows better seedling growth of above parameters. Minimum value of this parameter was recorded in henna leaf extract priming with humid invigoration in both ribbed gourd (COH 1) and bitter gourd gourd (CO 1).
RESUMO
Two-dimensional echocardiography (2D-echo) is sensitive in detecting floating bodies in the left atrium. Identification of a freefloating left atrial thrombus, as a source of embolus, is a common indication for 2D-echo. Screening for other cardiac conditions such as valvular heart diseases often, if not common, reveal floating bodies in the left atrium. The differential diagnosis of a floating body in the left atrium will be discussed.
RESUMO
Flavonoids, dietary antioxidant compounds may offer some protection against earlystage diabetes mellitus and its associated complications. The present study aimed to evaluate the effect of rutin on overall health of patients with diabetes mellitus. The effects of rutin were tested by using it as a supplement with their regular medications. The total trial period was of 120 days conducted with a gap of 30 days each. It consisted of 30 patients aging between 40-50 years, having diabetes mellitus since last 5 years. These patients were given Rutin Tablets for 60 days. Fasting Blood Sugar (FBS), Body Mass Index (BMI), blood pressures, lipid profile, serum urea and creatinine, electrolytes, SGOT (serum glutamic oxaloacetic transaminase), SGPT (serum glutamic pyruvic transaminase) and Alkaline phosphatase (ALP) were measured at baseline and then after every 30 days. Rutin tablets were stopped for next 60 days. All of above parameters were again measured on 90th and 120th day. The results showed that rutin decreased the levels of FBS, systolic and diastolic blood pressure, HDL, Serum Urea and creatinine significantly (P<0.05), whereas significant increase (P<0.05) in TGL, HDL, VLDL were seen. Decrease in the level of SGOT, SGPT, ALP and BMI is not significant.
