Abstract

To study the effects of leaf extract from Railway beggarticks and Ageratum conyzoides on seeds germination and growth of upland rice,six physiological and biochemical index including the percentage of seeds germination,root length,seedling height,the vigor of plant root,the activity of peroxide enzyme(POD) and hyperoxide dismutase(SOD) were determined.The results showed that the leaf extract of Railway beggarticks and Ageratum conyzoides had an inhibitory effect on seeds germination and the growth of upland rice.This water extract at low concentration reduced the percentage of seeds germination,Linhibited the root length and seedling height of young seedlings,depressed the vigor of root,increased the activity of peroxide enzyme(POD) and hyperoxide dismutase(SOD),and then inhibited the growth of upland rice.Ageratum conyzoides showed a great inhibitory effect than Railway beggarticks in the same concentration of leaf extract.
