对1270多份亚洲栽培稻各生态型地方品种及普通野生稻的分析表明,鉴别籼、粳及野生稻用萌动期种子检测酯酶同工酶效果较好,可出现16条酶带,其中10A为粳稻主特征带,11A为籼稻的主特征带,13A为Aus及一部分西南亚籼的主特征带,14A为普通野生稻的主特征带。10A、11A、13A、14A与栽培稻起源及籼粳分化密切相关,可作为区分籼粳的指标。本文还对国内外各研究者的酯酶同工酶分析结果进行了对比。 Analysis of more than 1270 Asian cultivated varieties of ecological landraces and common wild rice showed that the identification of esterase isoenzyme in indica, japonica and wild rice with germinating seeds was better, and there were 16 bands with 10A Is the main characteristic zone of japonica rice, 11A is the main characteristic zone of indica rice, 13A is the main characteristic zone of Aus and a part of southwest indica, and 14A is the main characteristic zone of common wild rice. 10A, 11A, 13A and 14A are closely related to the origin and indica-japonica differentiation of cultivated rice and can be used as an index to distinguish indica and japonica. This article also compared the results of esterase isozyme analysis of various researchers at home and abroad.
