Efficient method for breaking seed dormancy inlamb’s quarters (Chenopodiumalbum L.)

Abstract

Studies on seed dormancy in lamb’s quarters (Chenopodiumalbum L.)var. Ooty 1 (Ck 1) revealed that the freshly harvested seed possessdormancy for about 30 days. Thereafter, the seed started to germinateminimally (2 %) and reached 100 per cent on 165 days after harvest.However, the seeds were viable (100 %) from the day of harvest upto165 days. Therefore, the dormancy breaking treatments were imposedwhich effectively improves the germination of freshly harvested seeds.In which, soaking of seeds in ethrel @ 50 ppm for 18 h would overcomethe physiological dormancy with the maximum germination (86 %).
