摘要
本文对华北地区蓟属CirsiumAdans.16种植物的甲醇提取液紫外吸收光谱(UV)进行了比较研究。结果表明,蓟属植物的叶较其它部位的UV具有较好的稳定性和代表性,其光谱的特征可以作为属下分类的重要依据,其化学分类结果与形态分类基本一致。根据光谱特征,结合形态学及有关的细胞学和同工酶方面的资料,重新确立了Sect.Pseudo-Eriolepis(Nakai)Kitam.和C.segetumBge.的组级和种级地位,最后,作者进一步讨论了光谱特征在化学分类中的意义。
In this paper, 16 species of Cirsium Adans. ( Compositae) from North China were examined for their UV-spectra of methylic extraction from powdered leaf samples. The result shows that their UV-spectra are variable and so distinct as to allow the identification of individual sections and species. On the basis of the UV-spectra, 2 taxa, Section Pseudo-Eriolepis (Nakai) Kitam. and C. segetum Bge. are established, which is supported by the evidences from morphology, karyotype and isoenzyme. In addition, the taxonomic significance of the UV-spectrum has been discussed.
