Abstract

The effects of Cd on a halophyte of Doingying wild soybean (DY-03262) were studied by comparing it with a cultivated soybean (SN-11) via investigating photosynthetic activity, chlorophyll fluorescence and Cd concentrations in leaves after treatment with different concentrations of Cd (0, 50, and 100 μM) for 10 days. There were no significant differences in photosynthetic rate (PN), actual photochemical efficiency of PSII (ΦPSII), stomatal conductance (gs), and photochemical quenching (qP) between the both soybean species without Cd treatment, but they decreased greater in DY-03262 than that in SN-11 leaves after Cd treatment. The study demonstrated that the decrease in PN were significantly correlated with Cd concentrations in the leaves of both soybeans species. The greater decreases in photosynthetic activity of the DY-03262 were due to the higher Cd concentrations in its leaves.
