Abstract:

The increases of atmospheric CO₂ concentration and ultraviolet-B radiation(UV-B)have significantly affected the crop growth,development and physiological processes.In this study,the influences on some resistant indexes were analyzed under the condition of doubled CO₂ concentration,enhanced UV-B irradiation and their combination.Related experiments were carried out in the artificial climate room using super-nodulating mutant 0498 and non-nodulating soybean mutant 0701 as materials.The results showed that,for mutant 0701,the activities of SOD under the three treatments were decreased by 14.5%,17.4% and 25.5%,respectively;the content of MDA was decreased by 29.7% under doubled CO₂ concentration but increased by 18.4% under enhanced UV-B irradiation.For mutant 0498,under the three treatments,UV-B absorbing compounds were increased by 44.4%,39.0% and 71.9%,respectively;POD activities were increased by 27.3%,47.7% and 65.6%,respectively;the activity of SOD under enhanced UV-B was increased by 27.3%;the content of MDA was increased by 85.3% under enhanced UV-B,while only increased by 62.7% under the treatment of combination;the electrolyte leakage was increased by 12.7% only under enhanced UV-B.In conclusion,the resistance of 0498 was higher than 0701.Doubled CO₂ could enhance the resistance of soybean while enhanced UV-B caused significant response.However,the responses under the treatment of combination were more complex.
