The effect of the temperature, light and some growth regulators during inhibition phase on the seed germination of celery cv. "Golden Boy" was studied. The inhibitory effect at relatively high temperature (25 degree C) well known as "thermo-dormancy" was proven. In this condition, the germination was consistently improved by the use of gibberellin GA3 and 2-chloroethyl phosponic acid. Also, the thermo-dormancy was partially removed by the use of light during the first 24 h at 25 degree C. These results suggest that it is possible to enhance the germination of the celery seed under high temperature conditions by adopting these treatments at the time of commercial sowing in cell trays.
