该文综述了近 1 0年来菊属植物系统进化和菊花起源研究的主要工作 .通过综合分析比较形态学、细胞学、远缘杂交和分子系统学的研究结果 ,作者发现关于菊花起源有许多问题尚待研究 .菊属植物各种间种界的划分依然是这个属内需要探讨的问题 ,对广泛存在的种下变异的分析还远未完成 ,关于菊属植物染色体倍性变化仍是一个谜团 .目前基本可以肯定毛华菊为主要起源种 ,而关于起源方式则远未解决 .根据已获得的数据 ,作者提出栽培菊花的形成是以菊属植物高度网状的系统进化式样为背景的 .继续应用植物系统学的方法和原理展开深入研究将有助于对这一千古之谜的探讨
This paper summarizes the main work on the evolution and origin of the genus Chrysanthemum in the recent 10 years.A comprehensive analysis of morphological, cytological, distant hybridization and molecular phylogeography results, the authors found that there are many problems on the origin of chrysanthemum Yet to be studied.Differentiation of all kinds of species in the genus Jurassicus is still a matter to be explored within this genus and analysis of widespread species variation is still far from complete and the ploidy change of the genus Chrysanthemum remains a mystery At present, it is certain that Maohuaju is the main source species, but the way of origin is far from settled.According to the data obtained, the authors propose that the formation of cultivated chrysanthemums is based on the systematic evolution pattern of the highly reticulated Jujube plants. In-depth study of the methods and principles of phylogenetics will help to explore the mystery of the ages
