摘要:

在野外调查基础上,根据开花习性、花序类型、花色、花型、雌蕊发育状况以及枝条和叶片特征,对木犀属的品种进行分类研究。结果表明,木犀属共有品种177个,属于5个种(包括1个杂交种),其中桂花品种157个(四季桂品种群18个、银桂品种群57个、金桂品种群45个、丹桂品种群37个)、树品种12个、齿叶木犀品种3个、华东木犀品种2个、山桂花品种3个;讨论了品种分类等级和分类依据;订正了桂花品种群的学名。

Abstract:

Based on field investigation and analysis, the cultivars in Osmanthus were classified according to their blossoming habit, inflorescence types, flower colors, flower types, ovary developing status, and characteristics of branches and leaves. 177 cultivars were recognized, including 157 cultivars in O. fragrans (18 in Siji Group, 57 in Albus Group, 45 in Luteus Group and 37 in Aurantiacus Group), 12 in O. heterophyllus, 3 in O. ×fortunei, 2 in O. cooperi and 3 in O. delavayi. The principles and ranks for cultivar classification were discussed, and a classification system was proposed. The scientific names of 4 groups in O. fragrans were revised.
