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.
