摘要：A pot experiment was conducted to study the effects of cross-hybridization on biomass, photosynthetic pigment content, antioxidant enzyme activity and soluble protein content of Solanum nigrum and Solanum diphyllum . The results showed that under cadmium (Cd) stress, the plant biomass, photosynthetic pigment content, antioxidant enzyme activity and soluble protein content of hybrid ND ( S. nigrum male × S. diphyllum female) and DN ( S. diphyllum male × S. nigrum female) were all higher than those of S. nigrum. S. diphyllum was optimal, and hybrid ND was superior to hybrid DN. The POD activity of S. nigrum was higher than that of S. diphyllum , and the POD activity of hybrid ND and DN was significantly higher than that of parent.
