【摘要】 本论文是申请桂花品种国际登录权课题的组成部分。广西具有丰富的木犀属植物资源，其中，桂花是广西的区花和桂林市的市花，桂林还是中国历史上“五大桂花产区”之一。本文对广西的木犀属和桂花品种资源进行了调查研究，主要结论如下： (1)通过在广西植物研究所(IBK)标本馆查阅了广西木犀属植物标本的基础上，确认了广西有厚边木犀Osmanthus marginatus(Champ．ex．Benth．)Hemsl．、长叶木犀O．marginatus var．longissimus(H．T．Chang)R．L．Lu、牛矢果O．matsumuranus Hayata、小叶月桂O．minor P．S．Green、狭叶木犀O．attenuatus P．S．Green、短丝木犀O．serrulatus Rehd．、细脉木犀O．gracilinervis Chia ex R．L．Lu、网脉木犀O．reticulates P．S．Green、木犀(桂花)O．fragrans Lour．、石山桂花O．fordii Hemsl．等9种、1变种的分布。 (2)在查阅资料的基础上对广西木犀属植物的分布进行了分析，绘制了广西木犀属植物分布图。 (3)根据桂花研究中心统一的调查方法和桂花品种分类标准，初步确定广西有43个桂花品种，分属于4个品种群，四季桂品种群3个，银桂品种群21个，金桂品种群14个，丹桂品种群5个。其中，在各种资料已有记载的桂花品种17个，新确定桂花品种26个。 (4)在对各品种形态进行对比研究的基础上编制了4个品种群的品种分类检索表。 (5)在广泛查阅资料的基础上，根据实地调查，掌握了广西桂花的栽培分布情况，将广西桂花的分布划分为主要分布区、一般分布区和零星分布区，绘制了广西桂花分布图。 (6)总结了单干桂花的繁殖及栽培技术，以促进当地桂花的产业化生产。 (7)总结了广西有关桂花资源开发利用现状，如园林绿化、芳香工业、食品工业、药用等方面的资料。 最后，对广西木犀属植物资源和桂花品种资源状况及其开发利用现状进行了总结，并提出了相关建议。更多还原

【Abstract】 This paper is a part of the subject of the Application to International Registration Authority of Osmanthus fragrans Cultivars. There are abundant Osmanthus resources in Guangxi. Osmanthus fragrans, being the region-flower of Guangxi and the city-flower of Guilin, which is one of the five well-known Osmanthus bases, has been cultivated for a long time in this area. This paper deals with the classification of the genus Osmanthus and osmanthus fragrans, the main results are summarized as follows:(1)9 species and 1 variety are recognized as Osmanthus marginatus (Champ, ex. Benth.) Hemsl., 0. matsumuranus Hayata, O. minor P. S. Green, 0. attenuatus P. S. Green, O. serrulatus Rehd., O. gracilinervis Chia ex R. L. Lu, O. reticulates P. S. Green, O. fragrans Lour., O. fordii Hemsl. in Guangxi, by a specimen consulting in IBK herbarium.(2) The distribution of Osmanthus in Guangxi is analyzed, and a distribution map is drawn.(3) According to the uniform investigation standard and classification criteria proposed by the Research Center of Osmanthus, it is acquired that there are 43 cultivars of osmanthus fragrans in Guangxi, in which, 3 in Siji Group, 21 in Albus Group, 14 in Luteus group and 5 in Arantiacus Group. Among them, 26 cultivars are described as new.(4) 4 cultivars key are given for each cultivars Group, after a contrast study of morphological characteristics.(5) The distribution of sweet Osmanthus in Guangxi is divided into 3 types, the main distribution, the common distribution and the disperse distribution. The distribution map is given too.(6) The technology of breeding and cultivating single stem Osmanthus fragrans is summarized, which can promote its industrialisation.(7) The current status about development and application of Osmanthus fragrans are commented, including landscape, perfume industry, food processing and medicine application.Finally, the resources of Osmanthus and Osmanthus fragrans were concluded, the development and application of Osmanthus fragrans are introduced, some relevant suggestion is also given in this paper.更多还原
