Description |
The bulk seed lots of Madhuri and Priya were graded using four different sieve sizes viz., 3.50 mm, 4.50 mm, 5.00 mm and 5.25 mm slotted(s). The experiment was conducted at Department of Seed Science and Technology and NSP, G.K.V.K, U.A.S, Bangalore. Among the sieve sizes highest seed quality parameters such as 100 seed weight (18.46 g), seed size(7.019 mm), germination (88.44%), vigour index(2638) was obtained in 5.00 mm(s) sieve size with seed recovery of (78.53%) and lowest was found in 3.50 mm. The seeds of cv. Madhuri and Priya were treated with Melathion @ 2ml/kg, Neem seed kernel powder @ 5 g/kg and were stored in three different packaging materials (P1: Cloth bag, P2: Polythene bag (300 gauage) and P3: Polypouch bag) for a period of nine months. Between the varieties, Priya had better storability in polypouch bag (81.39%) than polythene bag (80.58%) and cloth bag(74.88%) and among the treatments Melathion @ 2ml/kg showed better seed quality parameters such as germination ( 80.63) , vigour index (1764) based on seedling length and dry weight (1629), total dehydrogenase activity(1.267), than Madhuri. Ageing studies revealed that One day accelerated aged seeds recorded germination (82.66%) which was same as that of seeds stored naturally for four month (86.66%), and two days aged seeds recorded germination (79.24%) equivalent to eight month (80.50%) and correlation studies for biochemical and physiological changes during storage showed that in both the packaging and treatments, electrical conductivity was negatively correlated while, germination, test weight, seedling vigour index I, TDH, protein content had positive correlation. |
