In orther to the effects of
seed priming with salicylic acid (SA) on germinability and seedling vigor of
fenugreek was used three salicylic
priming treatments (control, 1700 and
2800 μM) and accelerated aging test for 24 and 48 hours including control with no
aging at 95% relative humidity at at 45°C. It was
found that aging for 48 hours without
priming resulted in significant loss of mean germination percentage, seedling
length vigor, seedling weight vigor, germination speed, coefficient of germination speed, mean daily germination,
coefficient of germination uniformity, germination vigor, maximum mean daily
germination, and germination value. But, when the aged seeds were primed with
2800 μM SA, it significantly improved these
parameters so that germination percentage reached to 100% from 41%. In
contrast to these germination speed were observed in unprimed aged seeds for 48
hours. Moreover, priming with 2800 μM SA
of aged seeds for 48 hours increased their seedling tissue water percentage to
94.48%. Accelerated aging for 48 hours reduced seedling length and weight
significantly. The highest seedling length, plumule dry weight and seedling dry
weight were observed in seeds treated with 2800 μM SA.
