摘要
以7个早熟梨成熟叶片为材料,研究了不同品种叶片长、叶片宽、叶片长×叶片宽与叶面积的关系。建立了7个早熟梨品种叶面积回归方程,所有叶面积回归方程的相关系数和复相关系数均呈极显著水平,均可作为测算不同梨品种叶面积的回归方程,在具体应用时可根据所要求的精确度和测定时的工作量进行选择。7个早熟梨品种早酥、鄂梨1号、鄂梨2号、华梨2号、西子绿、翠冠及金水2号测算较为精确的叶面积回归方程分别为Y=42.338x1-603.5、Y=-34.297x1+0.939x1x2+1439.82、Y=15.548x2+0.547x1x2-545.26、Y=37.337x1+86.151x2-5187.31、Y=33.076x1+103.399x2-5691.59、Y=53.965x1+84.328x2-6700.49、Y=121.410x2-3703.6。
The correlations between leaf area and leaf length,leaf width,leaf length × leaf width were analyzed by measuring the climax leaves of 7 early-mature pear cultivars.The leaf area s regressive equations of 7 early-mature pear cultivars were established,and their correlation coefficients and compound correlation coefficients all reached the very significant level(P<0.01).The more accurate leaf area s regressive equations of Zaosu pear,Eli No.1,Eli No.2,Huali No.2,Xizilv pear,Cuiguan pear and Jinshui No.2 w...
