The effect of photoperiod on the flowering of Eruca sativa Mill. was studied. Plants were exposed to an 8-hrs photoperiod under natural daylight. The photoperiod was extended with 60 W incandescent lamps to give an 10-to 16-hrs, a day. Under photoperiods at and above 13-hrs, flower buds were initiated; the days from bud formation to flowering were shortened in plants grown under a 16-hr photoperiod, or if the night was interrupted for 2 hrs starting at midnight.
