【摘要】 收集13个金铁锁居群的植物学性状和气象因子组成一个灰色系统,从两个层面对这一系统进行了分析。从居群间的灰色关联分析可知,玉龙雪山居群、象山居群、九河居群和六德居群的金铁锁综合性状表现较为优异;其次是期纳居群、尼西居群、顺州居群和鹤庆居群;表现较差的是洱源居群、松坪居群、羊坪居群、中甸居群和得荣居群。若要对金铁锁进行引种驯化及高产栽培,应优选与玉龙雪山居群、象山居群、九河居群和六德居群生境相似的地点进行种植。从主要植物学性状和气象因子与产量的灰色关联分析可知,从植物学性状方面可侧重对根粗、根茎重和叶宽的选择,从气象因子方面可侧重从空气相对湿度、年降雨量和年均日照时数比较协调的地点加以选择。更多还原

【Abstract】 Grey correlation analysis was adopted to study the botanical characters and meteorological factors of 13 populations of Psammosilene tunicoides. The grey correlation analysis of different populations showed that the botanical characters comprehensive performance of Yulong snow maintain,Xiangshan,Jiuhe and Liude were excellent,the next were Qina,Nixi,Shunzhou and Heqing,the Eryuan, Songping, Yangping, Zhongdian and Derong were worse. So suitable areas for introduction and domestication of Psammosilene tunicoides should be selected that the habitat such as Yulong snow maintain,Xiangshan,Jiuhe and Liude. The grey correlation analysis of yield between main botanical characters and meteorological factors showed that the root diameter,root weight and leaf wide were important botanical characters,the relative air humidity,annual rainfall and average annual sunshine duration were main meteorological factors.更多还原
