摘要
桂花是中国古老的栽培花木之一,以臧德奎、向其柏发表的观赏桂花品种分类检索表为依据,对合肥地区的桂花品种进行了调查,共确定合肥地区桂花品种39个,隶属于四个品种群,其中四季桂品种群有品种4个,银桂品种群有品种8个,金桂品种群有品种21个,丹桂品种群有品种6个;据此发现了合肥地区桂花种质资源存在的问题:①花期短的秋桂品种多,而花期相对较长的四季桂品种较少。②苗木生产目标性不强。③桂花品种分类意识不强。④缺少专营性苗圃。
Based on the studies on cuhivar resources of sweet osmanthus in Hefei of Anhui Province, 39 cuhivars are classified into four groups, among them, 21 in Luteus Group, 8 in Albus Group, 6 in Aurantiacus Group, 4 in Siji Group. Each group is formulated a cuhivar classification system ,and characters of each cultivar are described. We found some problems existed in resource. The first , cuhivars of sweet osmanthus flowering in autum are more than the cuhivars of sweet osmanthus flowering in four seases. The second, the producers do not have clear targets of produce. The third ,the producers are lack of classification knowledges about sweet osmanthus. The last, there is not a garden which only cultivate sweet osmanthus. In view of these problems, the researchers should introduce more varieties of Siji sweet osmanthus from the other areas. To teach the producers some knowledges about classification of sweet osmanthus. To guide and help the producers construct the garden just for cultivating sweet osmanthus.
