摘要
桂花是中国十大名花之一,彩叶桂品种群作为桂花的新品种群,集绿化、香化和彩化三种功能于一体,在园林应用领域价值大、前景广。本文总结彩叶桂品种资源概况,发现目前通过审定的27个彩叶桂品种主要来源于播种苗的人工选择、扦插苗及芽变,多来自广西桂林地区,从色系角度可分为红色系和黄色系;同时对研究现状进行了梳理,发现彩叶桂在繁育与栽培方面研究较多,生理生化和分子生物学方面也做了一定研究,并对其今后的研究和应用前景进行探讨及展望,为今后彩叶桂的品种鉴定、保护及新品种开发和资源合理利用提供理论依据。
Osmanthus fragrans is one of the top ten famous flowers in China.As a new population of O.fragrans,the O.fragrans colour group integrating three functions including greening,aromatization and coloring has great application value and broad application prospect in landscape field.This paper summarizes the states of the cultivar resources of O.fragrans colour group,finding that the 27cultivars mainly derived from the artificial selection,cutting seedling and bud sport,and most of them came from Guilin,Guangxi,which could be divided into red series and yellow series from the perspective of color system.At the same time,this paper also reviews the current situation of researches,finding that there are many researches on breeding and cultivation while some researches focus on physiology,biochemistry,and molecular biology.Besides,the future research and application prospects are discussed.It provides theoretical basisfor the identification,protection and the development of new cultivars and rational utilization of resources of O.fragrans colour groupin the future.
