Abstract

To study whether the hybridizing could promote the growth of F1 hybrids of vegetables under heavy metal stress, a pot experiment was carried out to investigate the effects of reciprocal hybridizing on growth of F1 hybrids of two genotypes of Brassica juncea var. megarrhiza under cadmium (Cd) stress. The results showed that the reciprocal hybridizing of two genotypes of B. juncea var. megarrhiza promoted the growth of F1 hybrids to some extent under Cd stress. The photosynthetic pigment (chlorophyll a, total chlorophyll and carotenoid) contents of F1 hybrids were higher than both two parents. The antioxidant enzyme (POD, SOD and CAT) activities of F1 hybrids were between two parents. Therefore, different genotypes of B. juncea var. megarrhiza hybridizing could promote the growth of F1 hybrids under Cd stress.
