摘要:
为了解广西境内蕴藏的野生阴生观赏植物资源及珍贵种质,采取野外实地考察及标本采集鉴定相结合的方法,对广西全境分布的阴生和半阴生观赏植物资源进行研究。结果表明:广西野生阴生观赏植物有5个基本特点:种类丰富(162科485属1 309种)、种质资源珍贵(珍稀植物195种,广西特有植物136种)、生长基质多样(喜钙植物、喜酸植物和中间类型植物)、草本性状比值显著(草本植物约占总种数的66.1%)、野生资源贮藏量的多寡悬殊性。6个主要野生阴生观赏类群为:蕨类植物(43科240种)、兰科(37属126种)、百合科(21属82种)、苦苣苔科(17属63种)、秋海棠科(1属43种)、天南星科(12属30种)。研究结果可为合理开发利用广西野生阴生观赏植物资源提供参考。
Abstract:
In order to understand the wild and shade ornamental plant resources and valuable germplasm hidden in Guangxi,the shade and half shade plant resources in Guangxi were studied by the methods of field investigation and specimen collection identification. The results showed that the five basic characteristics of Guangxi wild shade ornamental plants:rich species(162 families,485 genera,and 1 309 species),precious germplasm resources(including 195 species of the valuable and rare plant,and 136 species endemic to Guangxi),diversity of growth soil texture(the calcicole,the acidophile and the intermediate plant),remarkable of the herbaceous ratio(the herb plants account for about 66.1%),and great disparity of wild resources distribution. The six taxa were as following:Pteridophyte(43 families,240 species),Orchidaceae(37 genera,126 species),Liliaceae(21 genera,82species),Gesneriaceae(17 genera,63 species),Begoniaceae(1 genera,43 species) and Araceae(12 genera,30 species). The results would provide a reference for the rational development and utilization of wild shade ornamental plant resources.
