Accelerated aging test is commonly used to obtain information
on seed vigor. It was also observed that under aging the germination of all seed lots was not affected when compared to the standard
test. Similarly, some researchers reported that water stress during
seed development had no effect on seed germination (Fougereux
et al., 1997; Samarah and Alqudah, 2011). Moreover, Vieira et al.
(1992) found that drought stress imposed at the beginning of seed
development or later at the full stage of development had no effect
on seed quality, as estimated by seed germination and accelerated
tests. The results of the standard and accelerated aging tests predicted the potential of seedling emergence of onion seeds under
water stress conditions. Seed quality can be considered as another
important trait affected by drought stress.
