摘  要：
[目的]为山茶花科学引种和育种目标性状的选择提供参考.[方法]运用相关性分析和主成分分析法提取影响山茶花观赏性的关键因子,对28个山茶花品种进行观赏价值的综合评价与观赏品种的筛选,构建观赏价值综合评价模型.[结果]山茶花各观赏性状之间存在显著相关性,花量、瓣数与花期呈极显著正相关,花色与新叶色呈极显著正相关;13个性状可综合为花量因子、花期因子、花径因子、色彩因子和叶形因子等5个主成分,累积贡献率达85.48%,具有生物学意义;28个品种评为3个等级,筛选出金碧辉煌、花宝珠、花鹤翎、花芙蓉、正黄旗、黄的旋律、小桃红、红叶贝拉、杰作等9个观赏价值Ⅰ级的品种,评价结果与实地观测效果基本一致.[结论]山茶花观赏价值主要受花量、花期、花径、色彩和叶形等因子的综合影响,花量和花期是最关键的影响因子,要重点选择花大色艳、花量丰富、花期长,或具彩叶特征,整体观赏性强的品种作为推广栽培或育种的优良亲本材料.

摘  要：
【Objective】For introducing and breeding new varieties.【Method】Ornamental value of 28 Camellia cultivars was evaluated,key appealing factors of Camellia were selected using the correlation and principal component analysis to construct a comprehensive evaluation model.【Result】Significant correlations among the various traits were observed.For instance,the flower count and petal number correlated significantly with florescence,and flower color with new leaf color.Those 13 characteristic traits were grouped into 5 principal components:flower count,florescence,flower diameter,leaf color,and leaf shape with a total cumulative contribution of 85.48%for the differentiation.Flower count and florescence were critical with biological significance as well.Based on their ornamental values,the 28 varieties were classified into 3 grades.The 9 varieties judged to be excellent were Jinbihuihuang,Variegated Precious Pearl,Variegated Crane's Feather,Variegated Hibiscus,Kigirohi,Senritsu-Ko,Otome,Red Leaf Bella,and Masterpiece.The results were basically in agreement with field observation.【Conclusion】The ornamental value of Camellia was governed by the flower count,florescence,flower diameter,leaf color and leaf shape with the flower count and florescence as the determinant factors.Thus,varieties with large and abundant flowers,long florescence period,and attractive leaves should be the choice for cultivation and breeding.
