前胡属(Peucedanum L.)血清分类学研究

Serotaxonomy of Peucedanum L. in China

利用琼脂板双扩散沉淀反应对我国前胡属（ＰｅｕｃｅｄａｎｕｍＬ．）１３种２变种的叶片蛋白质进行了血清学分析，根据血清相似性将所分析的种类分成５个类群，其中石防风〔Ｐ．ｔｅｒｅｂｉｎｔｈａｃｅｕｍ（Ｆｉｓｃｈ．）Ｆｉｓｃｈ．ｅｘＴｕｒｃｚ．〕、刺尖前胡（Ｐ．ｅｌｅｇａｎｓＫｏｍａｒｏｖ）和白花前胡（Ｐ．ｐｒａｅｒｕｐｔｏｒｕｍＤｕｎｎ）各自为一类群，其余种类分别以华北前胡（Ｐ．ｈａｒｒｙｓｍｉｔｈｉＦｅｄｄｅｅｘＷｏｌｆ）和华山前胡（Ｐ．ｌｅｄｅｂｏｕｒｉｅｌｏｉｄｅｓＫ．Ｔ．Ｆｕ）为代表分成二个类群。结合形态、地理等资料，分别讨论了各血清学类群的种间关系和分类学问题。

20～26Interspecific relationships of 13 species and 2 varieties of Peucedanum L. in China were studied by precipitation reaction with agar gel double diffusion for foliar proteins. According to the serological similarity, five serological groupings were detected by the cluster analysis and the polar ordination. These five groupings corresponded to P. terebinthaceum, P. elegans, P. praeruptorum; P. harry smithii which is a reprensentation of the grouping being 4 species and 1 variety, and P. ledebourielloides which is a reprensentation of the grouping being 6 species and 1 variety. High serological similarity occourred between P. harry smithii (including P. harry smithii var. grande) and P. ampliatum. P. mashanense and P. guangxiense formed a very close serological unit, perhaps they were original in Peucedanum in China. P. ledebourielloides and P. wawrae had high serological similarity, and can be regarded as a new section in Peucedanum. Distinct protein difference were detected in P. terebinthaceum and P. terebinthaceum var. deltoideum. Serological data supported that the division of P. terebinthaceum and P. elegans belonged to two sections of Peucedanum, respectively.
