同一区域不同分布高度葛萝槭表型性状变异分析

为了解同一区域不同分布高度葛萝槭种群表型变异程度及变异规律,对来自河北省灵寿县五岳寨地区3个分布高度葛萝槭种群进行单果质量、单果皮质量、果长、果宽、果厚、果实长宽比、单种质量、种长、种宽、种厚、种子长宽比及种子千粒质量等12个表型性状进行观测,采用平均值、变异系数、方差分析及相关性分析等方法进行分析.结果 表明:同一区...

Variation of Phenotypic Traits of Acer Grosseri with Different Heights in the Same Area

Using mean value,coefficient of variation,variance analysis and correlation analysis and other methods to analyse the single seed weight,single peel weight,fruit length,fruit width,fruit thickness,fruit length/fruit width,single seed weight,seed length,seed width,seed thickness,seed length/seed width and thousand kernel weight of Acer grosseri fruits and seeds from three populations Wuyue Village of Lingshou County,Hebei Province.In order to understand the phenotypic variation degree and variation rules of Acer grosseri populations.Result indicates that the 12 phenotypic traits of with different distibution heights have significant differences between different distribution heights and the same distribution height;the genetic variation coefficients of 12 phenotypic traits is 2.0339%-35.2534%,the largest is thousand kernel weight,fruit width is smallest,the phenotypic traits are rich in variation.The highest average coefficient of variation of the 12 phenotypic traits is at 1197.3 m,and the lowest is at 1486 m.The coefficient of variation increases with height within a certain distribution height range.The higher of altitude,the smaller coefficient of variation.The phenotypic characters and distribution of the fruit and seed of Acer grosseri are closely related,and the correlation between the phenotypic characters is not significant.Within a certain height range,the fruit and seed quality increases with the height.The moisture content is 11.1841%of seed,the coefficient of variation is 6.781%.
