中国几种特殊普通小麦酯酶同工酶研究

采用聚丙烯酰胺凝胶电泳法对中国几种特殊普通小麦的幼芽进行了酯酶同工酶分析。结果表明:同种不同来源的麦酶谱差异不大,较整齐一致,只有个别材料有酶带的增减及沾性强弱有别;对于不同的物种云南铁壳麦与西藏半野生小麦的酶谱很相近似,属同一类群,新疆稻麦慢带较模糊,少第3条酶带归属别一类群。

ESTERASE ISOZYME STUDY OF INDIGENOUS WHEAT TO CHINA

By means of polyacrylamide gel slab electrophoresis, the esterase isozyme of young buds from 24 accessions of indigenous wheat to China was analysed. The result showed that zymogran variation did not be found obviously among same species from different distribution districts; and zymogram variation could be found obviously among different species. Triticum aestivum ssp. yunnanenses Keng was geneticaly close related to Tibet semi-wild wheat. Both of them are in the same level of evolution and belong to one taxonomical group. Xinjiang rice wheat is a special group, having its own evolutionary process.
