Abstract:
In the present piece of work, the caryopses of two wheat varieties (HUR-468 and HUW-234) were taken to
study the effects of aging during germination. Accelerated aging (artificial aging) treatments were created
by keeping the seeds (with initial moisture content of 12%) at 40o
C and relative humidity of 90-95% for
24, 42, 72, 96, 120, 144, 168 and 192h periods. Seeds without any ageing treatment were considered as
control (T1
). The parameters like germination percentage, speed of germination (N), mean germination
time (MGT), shoot and root lengths, root numbers, fresh and dry weights, α-amylase activity and soluble insoluble sugar contents were studied upto 10 days after sowing (DAS) in artificially aged and non
aged seeds during germination. Result suggested that aging affects the whole process of germination of
seeds. The maximum values of the studied parameters were obtained from the 24h aged seeds followed
by control and 42h aged seeds in both the varieties. Among the two varieties HUW-234 showed better
performance for the above studied parameters.
