【Abstract】 The drought resistances of six varieties of three species of cool-season turfgrasses have been studied in this test. Compared their developing manifestations and living targets that have been measured under the stress of different consistency PEG-6000 solutions,there are different drought resistances of them. The result showed that the PLANTATION of TALL FESCUE kind having the best manifestations ,the deepest roots developing in the soil and the highest CAT activity,which indicated that it had stronger drought tolerance than others.更多还原
