Abstract
Abscisic acid at 1 × 10−4M concentration controlled the progress of the emerging radicle from germinating rape seeds and apparently restricted it to the dehydration tolerant phase. ABA treatment during germination followed by washing reduced the deleterious effects of drying the seeds following selection based on a newly-emerged radicle. Furthermore, the longevity of these low-moisture-content germinating seeds at a range of temperatures was improved by the ABA treatment. The viability of the treated seeds stored at −20°C was maintained for up to 100 days.
