MEASURING LEAF AREA IN PEAR TREE USING REGRESSION EQUATION METHOD

摘要: 用回归方程法测定梨树单叶面积,以长枝、随机及比例方法取样,取样数量50至100片,采用叶长乘以叶宽的回归方程测定较为适宜。

Abstract: Measuring a piece of leaf area in pear trees using regression equation method, it is suitable to use the regression equation of multiplying leaf length by the width, according to the methods of long-shoot sampling, random sampling and proportional sampling, and the leaf quantities being 50—100 pieces.
