英文摘要: The changes in growth, gas exchange, and stable carbon isotope value (delta(13)C) in soybean seedlings (Glycine max L. Merr. cv. Longdou No. 1) exposed to a 11.2 kJ m(-2) day(-1) biologically effective UV-B radiation (UV-B-BE, 280-315 nm) and 50 mg CdCl2 kg(-1) vermicular treatment, either alone or in combination were investigated under greenhouse conditions. Compared to the control, plant height and biomass, photosynthesis rates (Pn), water-use efficiency (WUE), and stomatal conductance (Gs) decreased significantly (P<0.05) exposed to cadmium (Cd) or UV-B radiation and combination. Leaf stable carbon isotope composition (delta(13)C values) decreased by Cd or UV-B radiation alone and in combination, delta(13)C were significantly correlated with changes in Pn, WUE and biomass. But Cd and UV-B in combination did not cause greater changes compared to Cd or UV-B radiation alone in many parameters. These results suggested that there was relatively little interaction of the two stresses. delta(13)C values may provide a reliable indication for growth, WUE, Pn or biomass of soybean seedlings when exposed to UV-B radiation and cadmium pollution.
