摘　　要：选用超干处理不同种子含水量为1.256%、2.579%、3.825%、4.474%和未处理9.030%（CK）的披碱草种子置于45℃下贮藏,测定种子发芽率,电导率,酶活性及丙二醛含量。结果表明,贮藏1年,CK的发芽率为0,超干各处理的发芽率为42%-44%,综合所测指标,含水量2.579%是披碱草种子在45℃贮藏的最适含水量,未处理的种子不利于保存。Physiological and biochemical characteristics of Elymus seed,with different water content（1.256%,2.579%,3.825%,4.474% and 9.030%）stored at 45 ℃ were tesed.The results showed that the optimum moisture content of Elymus seed,storedat 45 ℃ with interval of short term（1 year）,was 2.579%.Moreover,characteristics of Electric conductivity,SOD,POD,MDA and CAT activities of Elymus seed,with different water content stored at 45 ℃,were showed in the present paper as well.
