The prevention of dehydration injury in celery apium graveolens seeds by poly ethylene glycol abscisic acid dark and high temperature


, : The prevention of dehydration injury in celery apium graveolens seeds by poly ethylene glycol abscisic acid dark and high temperature. Physiologia Plantarum 55(4): 407-410

Celery seeds (A. graveolens L.) given a germination induction period (3 days imbibition at 17.degree. C in the light) could be prevented from germinating by up to 14 days subsequent exposure to high temperature (32.degree. C), polyethylene glycol (PEG), abscisic acid (ABA) or dark (22.degree. C). When the seeds were returned to 17.degree. C in the light, germination occurred and, except for the high temperature treatment, was more rapid compared to seeds given a germination induction period only. Celery seeds incubated for 3 days at 17.degree. C in the light and then air-dried at 20.degree. C germinated slowly when re-sown at 17.degree. C in the light, and achieved only 19% germination after 21 days. Exposing the seeds to high temperature, PEG, ABA or dark for up to 14 days before drying maintained seed viability and subsequent germination was faster. The longer treatment periods gave increased benefit, and PEG was the most effective treatment. The effectiveness of the treatments in inducing dehydration tolerance may relate to their ability to inhibit germination possibly via their prevention of cell expansion.
