对同工酶进行概述,介绍禾本科中几种主要作物利用同工酶酶谱的差异来鉴定品种、品系及检测种子纯度等有关研究。同工酶在一定时期的相对稳定性为测定种子的真实性提供了可靠依据。同工酶图谱实质上是植物性状在分子水平上的表现型。
The isozymes are summarized, and the differences of isoenzyme zymograms of several major crops in Gramineae are introduced to identify the varieties, strains and the purity of the tested seeds. The relative stability of isozyme in a certain period of time provides a reliable basis for the determination of the authenticity of the seed. Isozyme profiles are essentially phenotypic at the molecular level of plant traits.
