摘要
利用灰色关联度评价、熵权法计算权重对6种石斛(Dendrobium)进行观赏性评价。结果表明,鼓槌石斛、密花石斛在等权关联度、加权关联度上均位于前两位,具有较高的观赏价值,其余关联度排名分别为翅梗石斛、翅萼石斛、苏瓣石斛、黄花石斛。根据各项指标权重将6种石斛划分为观花类的鼓槌石斛、密花石斛,观叶类的翅萼石斛、黄花石斛,观茎类的翅梗石斛、苏瓣石斛,为石斛属植物在观赏价值开发利用和石斛属植物育种方面奠定了基础。
The grey correlation degree evaluation and entropy weight calculation weight were used to evaluate the ornamental evalua⁃tion of 6 kinds of Dendrobium species.The results show that Dendrobium chrysotoxum Lindl.and Dendrobium densiflorum Lindl.are in the top two in terms of equal weighted correlation degree and weighted correlation degree,and have high ornamental value.The other correlation degrees are Dendrobium trigonopus Rchb.f.,Dendrobium cariniferum Rchb.f.,Dendrobium harveyanum Rchb.f.and Den⁃drobium dixanthum Rchb.f..According to the weights of each index,6 Dendrobium species are divided into D.chrysotoxum and D.densiflorum of the flower-viewing category,D.cariniferum,D.dixanthum of the leaf-viewing category,D.trigonopus,D.harveyanum of the stem-viewing category.This research can laid the foundation for the development and utilization of ornamental value and breed⁃ing of Dendrobium species.
