Abstract:
This experiment was conducted by sand culture with controlling different manganese concentration to study the effect of manganese stress on soybean growth and yield.The results showed that:Manganese stress had no significant influence on soybean plant height at seedling stage,but significantly inhibited that at R2,R4,R6 and R8.Manganese stress significantly inhibited stem diameter at R2 and R4 and root length at R6,and no influence at the other stage.Manganese stress had no significant influence on leaf area at R4 and R6,and no influence at V4 and R2.Besides seedling stage,manganese stress significantly inhibited nodule number,nodule fresh weight,and nodule dry weight.Manganese stress significantly inhibited dry matter accumulation of leaf,stem,root,and whole plant,and dry matter accumulation of pod at R6 and R8,and seed yield.In conclusion,manganese stress had no significant influence on soybean growth at earlier growing stage,but significantly inhibited at the middle-later period,which finally caused seed yield significantly decreased.
