Application of Grey Relational Degree Analysis in Evaluation of Osmanthus Species

于2019年在福建省浦城南郊临江镇,对引种的8个桂花品种(堰红桂、醉肌红、天香台阁、佛顶珠、娥皇、晚金桂、玉玲珑、串银球)的单枝开花量、春梢分枝量、花色、香味性状、树型5个因子进行观测、分析、评价,以当地主导品种浦城丹桂作为对照;运用灰色关联度分析,筛选出适合本地发展的3个优良品种:堰红桂、串银球、娥皇,2个独特品种:醉肌红、晚金桂。

In 2019,in Linjiang Town,the south suburb of Pucheng,Fujian Province,the 5 factors of single branch flower amount,branch amount of spring shoot,flower color,fragrance character and tree type of 8 Osmanthus varieties(Osmanthus fragrans′Yanhonggui′,Osmanthus fragrans′Zuijihong′,Osmanthus fragrans′Tianxiangtaige′,Osmanthus fragrans′Fodingzhu′,Osmanthus fragrans′Ehuang′,Osmanthus fragrans′Wanjingui′,Osmanthus fragrans′Yulinglong′and Osmanthus fragrans′Chuanyinqiu′)were observed,analyzed and evaluated,and the local dominant variety Osmanthus fragrans′Puchengdangui′was used as reference by grey correlation analysis,three good varieties suitable for local development were selected:Osmanthus fragrans′Yanhonggui′,Osmanthus fragrans′Chuanyinqiu′,Osmanthus fragrans′Ehuang′,and two unique varieties:Osmanthus fragrans′Zuijihong′and Osmanthus fragrans′Wanjingui′.
