大穗黑麦草抗性的有关生理生化指标的研究

摘要

In this paper,biological properties of L. grandispicum Y.J.Fei were observed and its physio-biochemical criterion such as chlorophyll content,malondialdehyde content and ascorbic acid oxidase activity were measured. After comparing with wheat variety EN1 and EN4 in Hubei,the result suggested that the grass has a good resistance. And the new species can provide new wild species resource for wheat resistant breeding.%通过对大穗黑麦草生物学性状观察及测定叶绿素含量,丙二醛含量,抗坏血酸氧化酶活性等生理生化指标,并与湖北省当前推广的小麦品种鄂恩1号、鄂恩4号作比较,结果表明它具有较高的抗性,为小麦的抗性育种提供了新的野生种资源.
