In this study , actinomycetes isolated have been analyzed using polyphasic taxonomy technology including morphological and physiological tests , analysis of chemotaxonomy , dna g + c content and 16s rdna / rna sequencing 采用形态学、细胞化学、生理生化、 dnag + cmol及16srdna序列分析等多相分类的技术对所分离的部分放线菌进行了系统的分类研究。

In the thesis , the systematic relationships of acorus together with araceae and typhales are discussed on the basis of features from micromorphology , anatomy , pollen morphology and floral development , with the aid of the data from their embryology , cytology , chemotaxonomy and molecular biology . firstly , it is found that there are many obvious differences between acorus and araceae 本文用形态学、解剖学、孢粉学及花器官发生等方法，并借助胚胎学、细胞学、植物化学及分子生物学等方面的资料，比较研究了菖蒲属( acorus )与天南星科( araceae )及香蒲目( typhales )的系统关系。
