Abstract:
Using Paspalum natatu seed as test materials,the effect of soaking Paspalum natatu seed with lanthanum chloride solution at concentrations of 2,5,10,20,30,50,100,300,500,1 000 mg/L on its germination and physiological and biochemical characteristics were studied.The results showed that La3+ had effects on seed germination and physiological and biochemical characteristics of Paspalum natatu,and depended on the concentration of La3+.Within the range of 2-20 mg/L,La3+soaking increased vigor of seed and its amylase activities,and promoted the Paspalum natatu seedling leaf and root growth,and 20 mg/L of La3+ was the best.When La3+concentration was higher than 50 mg/L,seed vigor,amylase activities,seedling leaf and root growth was inhibited.Furthermore,it was found that the effect of La3+on the growth of underground part was much stronger than the ground part.
