Interactions between environment and traits and analysis of stability in new triploid clones of Populus tomentosa

  • 摘要: 目的为揭示与阐明三倍体毛白杨纸浆材新无性系在多点试验条件下的主要生长和材性指标遗传变异、无性系与栽培环境互作和稳定性信息,服务于各栽培地区的主栽品种选择。方法本文对设置在晋、鲁、豫5个试验点的三倍体毛白杨新无性系区域化对比试验林7年生无性系植株进行了木材基本密度和主干生长指标的调查分析,估算了无性系间遗传变异与稳定性参数。结果结果表明:栽培地点、无性系效应对三倍体毛白杨生长性状、木材基本密度以及主干生物量均有极显著影响;地点与无性系间的交互作用对生长性状和主干生物量具显著影响,对木材基本密度的影响不显著。三倍体毛白杨新无性系的木材基本密度重复力为0.92,略大于胸径(0.90)、树高(0.84)、单株材积(0.86)以及主干生物量(0.80)的重复力。通过生长性状、木材基本密度以及主干生物量的稳定性分析,筛选出高产且相对稳定的三倍体毛白杨无性系B303,两个木材基本密度大且稳定性好的无性系B331、B302。三倍体毛白杨生长性状和木材基本密度稳定性评价结果不一致,可能与两者间存在弱的负相关性有关。建议主干生物量可作为纸浆材新品种评价的重要指标。结论论文成果深化了对毛白杨材性变异与影响因子的认识,为优良纸浆材品种选择提供了技术参考,对促进优良品种的推广有积极指导意义。
