摘 要:在充分考虑影响南天竹观赏特性的各种因素和指标上,应用灰色关联度分析法,对湖南地区13个地理种源秋季观赏特性进行了综合评价,其中8个种源与理想种源的关联度大于0.5,说明湖南地区南天竹地理种源中绝大多数具有较好的观赏价值.并把关联度值与其变异系数进行相关分析.结果均为显著相关,因此,认为用灰色关联度方法能够较好地评价南天竹的观赏特性.并选出了3个观赏特性在湖南表现最好的优良南天竹地理种源,为科学、合理地选择园林观赏植物提供了可靠的理论基础和科学依据.13 different varieties district of Nandina in Hunan were evaluated comprehensively by grey correlative analysis method. A lots of factors and index were considered to impacting ornamental character of Nandina. The correlation degree of 8 different sources were more than 0.5, it showed that the ornamental value of Nandina domestica is higher in Hunan. Grey correlation degree and variation coefficient were relatively analyzed, the result showed that its is correlation notable. So grey correlative analysis method was a better way to comprehensive evaluation about ornamental characters of Nandina. Three Kinds of best Nandina in Hunan were selected, thus theoretically and scientifically it has provided the basis of choosing and applying Gardens ornamental plants.
