摘要
木兰科植物在植物系统分类学上具有重要地位,也是北半球亚热带森林的重要组成树种,主要集中分布于我国西南部和南部。系统研究四川省野生木兰科植物的形态特性、地理分布特点及其利用价值,结果表明:四川省野生木兰科植物资源丰富,有5属24种1变种,分布在盆周山地、川西南和川西高山狭谷的东南部,主要分布于川西高山狭谷的东南部,处于现代木兰科的分布、分化和起源中心的边缘;四川野生木兰科中,乔木树种23种,灌木2种;常绿成分13种,落叶成分12种。花色包括红色、淡红色、紫红色、紫色、黄色、淡黄色、黄绿色、白色和乳白色等,有些种类的花具有极浓烈香味,叶形奇异,果实独特,树形优美;乔木的干形好、材质优良、较速生。这些珍贵树种,在科研、园林绿化、林业等方面具有广阔的应用前景。
Magnoliaceae plants,which have important role in botanic systematic taxonomy and are also important trees in sub-tropic forests,mainly distribute in South and Southwestern China.This paper studies systematically the classification and geographical distribution and utilization of the wild Magnoliaceae plants in Sichuan Province.There are rich wild Magnoliaceae plants in Sichuan,and 5 genera 24 species 1 variety species with 23 species of arbors and 2 species of shrubs,and 13 evergreen species and 12 deciduous species,were distributed in the hills around basin and the southwestern Sichuan and the southeastern of the mountain and deep valley in western Sichuan.They mainly distributed in the southeastern of the mountain and deep valley in western Sichuan,situated in the edge of the core of the distribution and development and origin of mordern Magnoliaceae.Their flowers have many kinds of colors including redness,rosiness, fuchsia,purple,yellowness,straw yellow,kelly,white and milkiness,some flowers of them have strong fragrance.Their leaves and fruits are not ordinary,and their tree shapes are very beautiful.Arbors grow fast with good stem shape and good timber.These important trees will have wide application prosperity in the ways of research,garden ornament,forestry,etc..
