Abstract

This experiment was carried out with two garlic varieties, Amarante and Centenário, under greenhouse conditions in order to verify the effect of the photoperiod of 9, 12, 15 hours, and natural, on the bulbing of that vegetable. Plants exposed to photoperiod of 12 and 15 hours, received 9 hours of sunlight followed by incandescent light (180 lux, aproximately). Results show that long-day treatments hasten the bulb formation with reduction of the culture cycle, in both varieties. The increase of day-length caused decrease of bulb weight at the time of harvesting, as result of the shortening of the bulb’s growth stage. The occurrence of bulbing in all treatments indicated that the critical photoperiod is lower than 9 hours, in both varieties.
