日本落叶松木材性状与生长曲线参数的关系及其种源变异对降水的响应
Provenance variations in wood traits of Larix kaempferi and their relationships to growth curve parameters and precipitation
了解木材性状的遗传变异及其与生长性状和环境变量的关系对林木复杂性状的遗传改良至关重要。本研究的目的是调查木材性状的变异及其与生长曲线参数的关系,并确定影响木材性状的主要气候因子。测定了来自 6 个种源 450 株日本落叶松的 15 个木材解剖和木材化学性状及生长性状。采用线性混合模型和 Pearson 相关分析估计这些性状的遗传参数以及木材性状与树高和胸径生长曲线参数的相关性。采用线性回归分析和 Mantel 检验来检验气候变量与木材性状之间的关…查看全部>>
Understanding the genetic variation in wood traits and their relationships to growth traits and environmental variables is essential for the genetic improvement of forest tree species.The aims of this study were to investigate the variation in wood traits and their relationships with growth curve parameters and to identify the main climatic factors affecting wood traits.Fifteen wood anatomical and wood chemical traits and annual growth traits were measured i…查看全部>>
