摘要
对四川的22份野生扁穗牛鞭草进行过氧化物酶同工酶分析,结果表明:(1)与品种“广益”、“重高”相比,野生材料有较丰富的遗传多样性;(2)Rf=0.069、0.610、0.937三条带是所有材料共有的,但是否为扁穗牛鞭草的特征带尚需要进一步研究;(3)聚类分析结果表明,来源相同、生境相似的野生材料的亲缘关系较近,但来源相同、生境不同的材料的酶谱有较大差异。
wild Hemarthria compressa. materials of Sichuan were studied.The result showed:①Compared with 'Chonggao'and'Guangyi',the wild materials exhibited richer genetic diversity.②Three bands at Rf=0.069,0.610,0.937 appeared in all materials, including of wild materials and 'Chonggao'and'Guangyi'.But further studies should be continued in order to detect whether the bands are characteristic band of Hemarthria compressa.③ There were closer relative among materials from same collection site and similar habit.But among the materials from same collection and different habit,the zymogram showed more variance.
