Under adversity, turfgrass adapt to environment by change extraneous shape, osmoregulation, dehydrate protection ,change membrane, increase enzyme activity and so on. The mechanism of salinity and drought tolerance of turfgrass and the effect of moisture and salinity menace on the growth and biochemical or physiological changes (membrane permeability、activity of SOD、POD、CAT、 free praline etc.) of turfgrass are introduced in the article. Meanwhile adaptive mechanism of turfgrass to drought and salt stress an...
