摘　　要：为给马尾松(Pinus massoniana)产脂性状的遗传改良提供参考,以马尾松种子园无性系及半同胞家系子代为材料,通过分析树体因子、采割因子与产脂量的相关性,解析影响松脂产能的主要因素;设置产脂力1、产脂力2、期望日均产脂量、校正产脂力1和校正产脂力2等5个松脂产能参数,分析和评价产脂能力。结果表明,树冠面积和树木径向生长量是影响产脂力的主要因子;采用期望日均产脂量、校正产脂力1和校正产脂力2进行产脂力评价更为科学可靠。校正产脂力1和校正产脂力2的狭义遗传力分别为0.16和0.11,明显高于期望日均产脂量的狭义遗传力,更适用于评价高产脂的遗传材料。校正产脂力1适用于密度较小、光照充足的林分;校正产脂力2适用于郁闭度较高的林分;期望日均产脂量与树体生长因子相关性最强,较适合作为材脂兼用遗传材料的评价指标。In order to provide reference to genetic improvement of rosin traits of Pinus massoniana,taking clones and half⁃sib progeny of P.massoniana in seed orchard as materials,main factors affecting rosin produc⁃tion capacity were analyzed by analyzing correlation among tree body factor,cutting factor and rosin yield.Ros⁃in production capacity was analyzed and evaluated by setting rosin production capacity 1,rosin production ca⁃pacity 2,expected daily average rosin production,corrected rosin production capacity 1 and corrected rosin pro⁃duction capacity 2.Results showed that crown area and radial growth of trees were main factors affecting rosin production capacity.It was more scientific and reliable to evaluate rosin production capacity of P.massoniana with expected daily average rosin production,corrected rosin production capacity 1 and corrected rosin produc⁃tion capacity 2.Narrow-sense heritabilities of corrected rosin production capacity 1 and corrected rosin produc⁃tion capacity 2 were 0.16 and 0.11 respectively,which were significantly higher than that of expected daily aver⁃age rosin production and were more suitable for evaluation and selection of high-yield genetic materials.Cor⁃rected rosin production capacity 1 was suitable for stands with low density and sufficient light,and corrected rosin production capacity 2 was suitable for stands with higher canopy density.Correlation between expected daily rosin production and tree growth factors was the strongest,so expected daily average rosin production was more suitable to be used as evaluation index of genetic materials for both wood and rosin genetic materials.
