The effects of intercropping with four floricultural accumulator plants (Helianthus annuus, Cosmos sulphureus, Cosmos bipinnata, Impatiens balsamina) on photosynthesis of grape seedlings under cadmium (Cd) stress were studied by the pot experiment, and the photosynthetic pigment contents, photosynthetic characteristics and soluble sugar contents in grape were determined. The results showed that intercropping with C. bipinnata significantly improved the chlorophyll a, chlorophyll b, total chlorophyll and carotenoid contents of grape seedlings. The net photosynthetic rate (Pn), transpiration rate (Tr), stomatal conductance (Gs), CO2 concentration of intercellular (Ci) and value of pressure deficit leaf (Vpdl) were increased by intercropping with C. bipinnata compared with the monoculture. Intercropping with C. bipinnata significantly increased the soluble sugar content in leaves of grape seedlings. Therefore, intercropping with C. bipinnata could improve the photosynthesis of grape seedlings under Cd stress.
