番茄叶面积测量方法的研究

Study on method to measure tomato leaf area

建立了番茄品种“coun ter”的叶面积与叶长、叶宽和叶长宽乘积的线性回归和幂函数回归方程。结果表明,番茄叶面积与相应指标呈极显著回归关系,建立番茄叶面积回归方程时应分叶片大小来进行,并且应根据残差分析来划分大小叶范围。通过比较认为,叶面积与叶长宽乘积的一元线性回归方程和叶长的幂函数回归方程均适用于叶面积的估算,并给出了番茄品种“coun ter”的叶面积回归方程。

Liner and exponent function regression equations were established by leaf area with leaf length,leaf width and the product of both with tomato variety ＂counter＂. The results showed that there was significant correlationship between leaf area and its related factors. The establishment of regression equations should be based on the size of leaves and should be divided according to the residual plot. Liner regression equations of leaf area on the product of both and exponent function regression equations of leaf area on leaf length were considered suitable to estimate leaf area. And regression equations Qf the variety ＂counter＂ were also given in the report.
