摘要
运用相关与回归分析的数理统计方法对盛果期红星苹果一年生枝叶面积与木质部横截面积两个因素的分析表明:其正相关达到高度显著标准,其相关系数r=0.9850求得全树叶面积依主干木质部横截面积的直线回归方程即经验公式=33.8062+2104.
Statistics analysis indicated that there was a highly siginificant positive correlation (r=0.985^(**)) between the leaf area and the transverse section of hadromestome of annual branch of Hong Xing apple at full fruit period and the regression equation of the transverse section of trunk stem hadromestome on the leaf area of whole tree was calculated as follow: y=33.8062+2104.3564x
