桂花品种分类系统研究

Studies on resource and taxon of Osmanthusfagrans cultivars.

通过对目前所知的桂花品种进行详细观察和比较研究发现,四季桂与桂花的区别非常明显,进而从形态性状、习性和DNA水平上分析了四季桂与桂花的亲缘关系,确定了四季桂的分类地位,并进一步建立了桂花品种分类的新系统.

According to our miticulous observation and comparative study of of all the cultivars, the difference between Osmanthus fragrans var. subpaniculatus and Osmanthus fragrans is guite obvious of all the cultivars Sweet Osmanthus presently known. The affinity relationship between Osmanthus fragrans var. subpaniculatus and Sweet Osmanthus is analysed according to their morphylogical features, habits and their charcteristics on level of DNA and each taxon status is examined. A new taxon system of cultivars of Sweet Osmanthus is established.
