This experiment take zoysia as experimental materials,which is treated with PEG of different concentration(3% (nutrient + 0.03 g/ml PEG10000),6% (nutrient + 0.06 g/ml PEG10000)) to simulate drought stress.The purpose of this experiment is to study the contents change of chlorophyll,proline,and MDA in the leaves of zoysia.The study finds that the damange of zoysia under drought stress increases over time and the increase of drought stress level.In the soils of different gradient,the physiological index and biochemical indicators vary in the leaves of 4 kinds of zoysia.As stress time and stress level increase,malondidehyde and proline increases,while the content of chlorophyll drops.
