| Abstract: | The effects of soaking seeds with different concentrations of uniconazole on the photosyntheticcharacters of maize seedlings were studied. The results showed that uniconazole treatment increased PEP car-boxylase activity and specific leaf weight, enhanced chlorophyll content and chlorophyll a/b ratio, and im-proved net photosynthetic rate in the leaves at three to seven leaf stage, and 40 mg.kg-1 was best. |
