本文对分韭、山韭和韭的两个栽培品种的叶片和根尖酯酶同工酯酶谱进行了分析研究。叶片酯酶同工酶分离出14条酶带;根尖酯酶同工酶分离出20条酶带。几种韭间酶谱类型差异显著,而品种间酶谱类型差异较小。同时,对分韭的分类问题进行了探讨。 In this paper, the esterase isoenzymes of leaves and apices of two cultivars of Allium, Allium and Allium were analyzed. Fourteen isozymes were isolated from the leaf esterase isoenzyme and twenty isozymes were isolated from the apical esterase isozyme. There were significant differences in the types of zymogram between the two species, while the differences in the zymogram types among varieties were relatively small. At the same time, the classification of sub-leeks was discussed.
