摘要(Abstract):
运用数量遗传学的原理和方法,分别剖析了白花泡桐接干强度与树高、胸径和材积生长,接干后的分枝强度与整个树冠结构的遗传相关和在型相关。结果表明,泡桐接干能力对生长,和对树冠结构都有重要的影响.
The theory and methall of quantitative genetiCS are used analysizing the trunk extension strength and tree height,breast diameter and volume growth of Paulownia fortunei and the genetic and phenotypical correlarions of its branching strensth after trunk extension with the whole erown structure.The rasults have shown that the trunk extension ability of Paulownia fortunei has a significant effect on its growth and crown structure.
