Variation Analysis on Leaf Traits of Horsfieldia pandurifolia
摘要
Abstract
The 14 leaf traits of two-year seedlings from 8 Horsfieldia pandurifolia families were determined,and the genetic variations of leaf traits among different families and within the family were analyzed.The results showed that varying degrees of genetic variations existed in leaf traits among families and within the family.The average range of variation coefficient in family was from 8.82％ to 29.94％,among families was from 4.75％ to 30.30％.The ratio of the leaf width on the left of main vein to leaf width and leaf vein number had the minimum variation.Variations of leaf area and leaf base angle were larger.Highly significant difference of leaf traits (except for the ratio of the leaf width on the left of main vein to leaf width) existed among families and within the family.The phenotypic differentiation coefficient among families (43.18％) was slightly lower than within the family,the main source of variation came from the family which indicated that the adaptive range of the living environment for H.pandurifolia.was relatively narrow.There were intricate relationships in leaf traits,mostly reached significant or extremely significant correlation level.Principal component analysis showed that the leaf traits variations of H.pandurifolia mainly were decided by three comprehensive factors,including leaf size,shape and texture.关键词
