【摘要】 本文以国内兴安落叶松[Larix gmelinii(Rupr.)Rupr.]天然分布区内17个种源(47°10′—52°25′N,119°57′—130°25′E)苗期(1a生)、幼林期(7a生)的生长、物候、抗性等主要性状为材料,采用方差分析、相关分析、偏相关分析和回归分析等方法研究了兴安落叶松种内地理变异的规律和模式,并结合凉水参试点7a生长性状初步选出了当地及毗邻地区的最佳种源。更多还原

【Abstract】 Based on the attributes of growth, phenology and resistance of seedling stage (1 year old) and juvenile stage (7 year old) from 17 natural provenances of dahurian larch in its distribution areas, this paper by means of the analysis ot variance, correction, partial-correction and regression, demonstrated the patterns of intraspecific geographic variation, and selected the best provenance of the species for Liangshui Experimental Forest Farm and its neighbourhood.更多还原
