EFFECT OF La-Gly ON PLANT HARMED BY SIMULATED ACID RAIN |
| |
| Abstract: | Ecophysiological effect of La Gly on Acer plamstum harmed by acid rain was studied.When Acer plamstum was sprayed with 30 mg L -1 La Gly once ,the harmfulness to Acer plamstumAcer plamstum by acid rain at pH 3.5 was reduced.The results indicated this was related to that La Gly could raise photosynthetic rate and chlorophyll content,reduce malondialdehyde content,decrease cell membrane permeability and keep the stability of cell juice pH value,and maintain the activity of CAT,POD and dehydrogenase in Acer plamstumAcer plamstum. |
