Abstract:
The emergence of celery (Apium graveolens L. cv. Utah 52-70) seeds was promoted by growth regulators when exposed to high temperatures during the germination period. The growth regulators were applied to dry seeds prior to sowing, by means of the organic solvent dichloromethane (DCM). A mixture of gibberellins A 4 and A 7 (GA 4/7) strongly enhanced emergence at a high day-time temperature of 35°C alternating with night temperatures of 20°C and 25°C; however, emergence was very poor when the night temperature was raised to 30°C. Under the latter regime, only mixtures of GA 4/7 with 6-benzylaminopurine (BA) or with 2-chlorophosphonic acid (ethephon) promoted seed emergence. However, BA and ethephon applied separately or in combination were much less effective in enhancing seed emergence without the addition of GA 4/7, under all the temperature regimes. © 1974 OXFORD UNIVERSITY PRESS.
