摘要：A pot experiment was conducted to study the effects of intercropping Vigna umbellata and Vigna radiata on photosynthetic pigment contents in Cyphomandra betacea seedlings under cadmium (Cd) stress. The result showed that under Cd stress, all intercropping treatments increased the chlorophyll a, chlorophyll b, carotenoid and total chlorophyll contents of C. betacea, especially the intercropping with V. umbellata which was highest in contents of chlorophyll a, chlorophyll b, carotenoid and total chlorophyll of C. betacea. On the contrary, all intercropping treatments decreased the chlorophyll a/b of C. betacea compared to the monoculture and intercropping with V. umbellata was lowest. Therefore, intercropping with V. umbellata could be the best choice to increase the photosynthetic pigment C. betacea under Cd stress.
