Abstract
In this study, we determined the effect of polyploidization induced by colchicine on the germination power of Trigonella maritima seeds. Germinated seeds of diploid plants of T. maritima were immersed in 0.05% colchicine solution for 4 h and then sown in pots in natural conditions. The seedlings from these seeds were compared with those of untreated seeds. The colchicine significantly increased the DNA content in polyploid seeds. Polyploidy increases the size and weight of seeds. The germination % in polyploid seeds was 90.52% compared to only 41.67% in diploid seeds
