摘要：
A pot experiment was conducted to study the effects of intercropping with four Bidens species (Bidens bipinnata, Bidens pilosa, Bidens parviflora and Bidens biternata) on photosynthesis and soluble sugar content of grape seedlings under cadmium (Cd) stress. The result showed that net photosynthetic rate (Pn), stomatal conductance (Gs), CO2 concentration of intercellular (Ci) and transpiration rate (Tr) were decreased compared to monoculture. The soluble sugar content in roots and shoots significantly increased by intercropping compared to monoculture. Therefore, intercropping with four Bidens species inhibit the photosynthetic ability but improve the resistance to Cd stress of grapes.
