| 摘 要： | 本试验对柿树单叶面积测定方法进行了研究,求得估算柿树单叶面积的回归方程:(?)=-0.84382+0.67697X(X为叶片长宽乘积值)和(?)=0.00373-0.88004X_1+1.25042X_2+0.69712X_3(X_1为叶长、X_2为叶宽,X_3为叶片长宽乘积值),其中以后一方程测定结果更精确.另一分析结果表明: 用方格板和光电叶面积仪测定柿树单叶面积与测定结果精确度高的画纸称重法相比差异不显著.

| Abstract: | Linear regression equations to evaluate the area of persimmon single leaf were established. They are y = -0. 84382 + 0. 67697X and y = 0. 00373 - 0. 88004X,+ 1. 25042X2 + 0. 69712X3(X1 stands for length of leaf,X2 wide of leaf and both X3 and X are product of the length and the wide). Comparing the two equations.the later one was more precise. The result obtained also indicated that there were no significant diversitis between the methods of squared board electronic leaf planimeter and weighing paper when they were used to measure the leaf area. |
