RESPONSES OF WILD CELERY (APIUM GRAVEOLENS) SEEDS TO LIGHT AND TEMPERATURE
Iranian wild celery has diverse uses including pharmaceutical, food and condiment and flavoring agent. An experiment was carried out to investigate seed germination responses of wild celery at two light conditions (white light and darkness) at different temperature regimes (15, 20 and 25°C). The results showed that percent germination and rate of germination were affected by both light conditions and temperature regimes. The percent germination was greater and rate of germination was faster under light treatment than in darkness. The percent germination at 15°C was higher than at the rest of the temperature regimes. The rate of germination was faster at 20°C compared with the lower and higher temperatures. There was a significant interaction between the light condition and temperature; there was an increase in the percent germination when seeds incubated in the light at 20°C. The rate of germination was not affected by interaction between the light condition and temperature regimes. From the results of this investigation, it can be concluded that the wild celery seeds are dormant when incubated at high temperatures in the absence of light. This dormancy is broken by exposure to light.
