摘要：
The effects of cadmium (Cd) stress on photosynthetic characteristics of grape seedlings were investigated through a pot experiment. The results showed that with the increase of Cd concentrations, the photosynthetic pigment content and net photosynthetic rate decreased. The transpiration rate, CO2 concentration of intercellular and stomatal conductance increased under Cd stress compared with the control, but water use efficiency decreased. With the increase of Cd concentrations, the vapor pressure deficit of leaf had the trend of increasing when the dose of Cd was not more than 10 mg/kg, and decreased when the dose of Cd was higher than 10 mg/kg. Therefore, Cd treatment could inhibit the photosynthesis of grape seedlings.
