摘要
用聚丙烯酰胺凝胶盘状电泳技术对中国苋属（ＡｍａｒａｎｔｈｕｓＬ．）植物１３种的酯酶同工酶谱进行了研究。结果表明：苋属植物酯酶同工酶有２条属的标志带，在生化水平上认为是一个自然的分类群；根据酶带Ｒｆ值及相似值，讨论了苋属种间的亲缘关系，认为栽培种类繁穗苋、尾穗苋和千穗谷亲缘关系相近；根据同工酶产生与进化的关系。
Isozymes of esterase of 13 species in genus Amaranthus were analyzed by using polycrylamide gel electrophoresis. As a result, esterase isozyme patterns show 2 representitive bands, and we think Amaranthus is a natural classification group. The taxonomic significance of esterase isozymes were discussed based on the Rf values and the similarity values of isozyme patterns. In the cultivated forms A. paniculatus, A. caudatus and A. hypochondriacus have a certain relationship. According to the relationship of isozyme product and evolution we consider section Amaranthus in more evolutionary than section Blitopsis .
