摘　　要：【目的】研究植物表型性状特性及其影响因素可为揭示物种对特定生境的生存偏好及人工栽培提供理论依据。【方法】以贵州省5个天然豹皮樟种群为研究对象,通过野外采集代表性植株叶片测定其表观参数,制作切片观察和测定解剖结构参数,并收集分布区环境因子数据,利用方差分析和相关分析法阐明叶片性状变异特性及其影响因素。【结果】开阳和习水种群叶片较宽大,各种群间变异度(48.48%)大于种群内(27.19%)。豹皮樟叶片为典型异面叶,其中开阳种群叶片解剖结构最发达,各种群叶片解剖结构参数存在显著变异性(69.55%)。豹皮樟叶片表型和解剖结构参数与多个环境因子显著相关,主成分分析表明二者受环境因子影响力的解释度分别为82.70%和81.56%,其中气温和降水量是主要的影响因子。【结论】豹皮樟资源保护和人工选育时宜选择开阳种源,于降水充沛且气温较高的区域开展人工栽培。【Objective】Research on plant phenotypic traits and their influencing factors could provide a theoretical basis for revealing the survival preference of species to the specific habitats and artificial cultivation.【Method】Five natural populations of Lista coreana var.sinensis were selected as the research objects in Guizhou province,China.The representative individuals’leaves were collected for measuring their apparent parameters,and then their sections were made to observe and determine the anatomical parameters.Meanwhile,the data of environmental factors were collected,and the characteristics of leaf phenotypic variation and its influencing factors were analyzed by ANOVA and correlation analysis.【Result】The leaves of Kaiyang and Xishui populations were wider,and the variation among the populations(48.48%)was greater than that within the populations(27.19%).L.coreana var.sinensis was a typical heterofacial leaf.The leaf anatomical structure of Kaiyang population was the most developed.There were significant variations(69.55%)in leaf anatomical parameters among five populations.The leaf phenotypic and anatomical parameters were significantly correlated with many environmental factors,which principal component analysis showed that the explanations of environmental factors were 82.70%and 81.56%,respectively.Meanwhile,temperature and precipitation were the main factors affecting leaf phenotypic parameters.【Conclusion】The kaiyang population should be selected for resource conservation and artificial breeding,and artificial cultivation is suitable for areas with sufficient rainfall and high temperature.
