随生境梯度变化的千叶蓍样本功能性状可塑性分析

Functional Trait Elasticity Analysis of Achillea millifolium Samples in Habitat Gradients

本文对试验田移栽的千叶蓍(Achillea millifolium)与野生千叶蓍样本功能性状可塑性变化进行分析。结果表明,移栽千叶蓍根生物量、茎生物量、叶生物量、花生物量、高度相对野生千叶蓍相应值均显著(P<0.001)增加,根长差异不显著(P=0.250);移栽千叶蓍根生物量分配显著高于野生千叶蓍根生物量分配(P<0.001),茎生物量分配、叶生物量分配和花生物量分配差异不显著;移栽千叶蓍花冠面积与其小花数、花生物量、总生物量和高度成显著相关(P<0.001)。

The functional trait elasticity between the cultivated and the wild growingAchillea millifolium samples was analyzed in this paper.The root biomass,stem biomass,leaf biomass and height of the cultivated samples were significantly (P<0.001)higher than that of the naturally growing samples,significant difference was not found in root length (P=0.250).The root biomass allocation of the cultivated samples was significantly higher than that of the naturally growing samples (P<0.001).Significant difference was not found in the resource allocations of the stem,leaf and flower.The corolla areas of the cultivated samples were significantly correlated with the flower number,flower mass,individual biomass and height (P<0.001).
