Effects of UV-B Radiation and Water Stress on Soybean Yield

Soybean Dongnong 47 was subjected to the experiments of increasing UV-B radiation and water stress on soybean yield components in different growth periods. The results showed that 100-seed weight greatly increased during the early stage of pod filling in the treatment of weak UV-B radiation,seed number per plant as well as seed weight per plant and Dongnong47 yield also increased,while the yield and yield components of Dongnong47 during the blossom to mature period were negatively affected in the treatment ...
