Abstract

A pot experiment was conducted to study the effects of cadmium (Cd) stress on photosynthetic characteristics of Cyphomandra betace seedlings. The annual C. betacea seedlings were treated with Cd of different concentration gradients (0 - 20 mg/kg). The results showed that with the increase of soil Cd concentration, the chlorophyll a, chlorophyll b, total chlorophyll and carotenoid content of C. betacea decreased, the net photosynthetic rate, stomatal conductance, CO2 concentration of intercellular, transpiration rate and light use efficiency decreased, the vapor pressure deficit of leaf and water use efficiency increased, compared with the control. Therefore, Cd stess could effect the photosynthesis of C. betacea seedlings significiently, and had a bad influnence on their growth.
