| 摘 要： | 以6年生日本栗品种＂辽栗10号＂与＂大峰＂为试材,对其叶长、叶宽、单叶面积、单叶干重、冠幅、冠高、单株叶片生物量进行了测定。研究不同品种间叶片长宽比值和比叶面积的差异性,叶片长、叶宽和叶片长宽乘积与单叶面积的相关性以及冠幅、冠高与单株叶片生物量的相关性。结果表明：不同品种间叶片长宽比、比叶面积均无显著差异;对日本栗叶长、叶宽、叶片长宽乘积与单叶面积进行一元回归方程拟合,决定系数与修正决定系数均达极显著水平（P〈0.0001）,其中以叶片长宽乘积与单叶面积的一元二次回归方程回归效果最好,决定系数达0.987 9,修正决定系数达0.987 7;单株叶片生物量与冠幅面积和冠高的二元线性回归关系达极显著水平（P〈0.0001）,决定系数达0.997 2,修正决定系数达0.996 4。在生产上,可以通过测量冠幅面积、冠高计算出单株叶片生物量和叶面积指数,该方法操作简单,具有较高应用价值。

| Abstract: | In this study,two cultivars of Castanea crenata,Liaoli No.10 and Dafeng were token as test materials.Based on the measurement of leaf length,leaf width,single leaf area,single leaf dry weight,crown width,crown height and the leaf biomass of individual plants,the reaches were carried out on the difference in leaf length-width ratio and specific leaf area of different cultivars,the relationship of leaf length,leaf width and the product of leaf length and width with leaf area,and the relationship of crown widt... |
