茶花叶面积测量方法的研究

Study of Measure Method on Camellia Leaf Area

运用SPSS13.0建立了茶花品种"七心红"的叶面积与叶长、叶宽和叶长宽乘积的线性回归方程。结果表明:茶花叶面积与叶宽、叶长宽乘积呈极显著回归关系,与叶长回归关系不显著,通过比较认为,叶面积与叶长宽乘积的一元线性回归方程、与叶宽的一元线性回归方程和与叶宽叶长宽乘积二元线性回归方程均适用于叶面积的估算,并给出了叶面积回归方程。

Liner regression equations were established by leaf area with leaf width and the product of leaf length and leaf width with tomato variety ＂seven red＂, The results showed that there was significant correlationship between leaf area and its related factors except leaf length. Multiple regression equations of leaf area on the product of leaf length and leaf width and regression equations of leaf area on leaf width were considered suitable to estimate leaf area. And regression equations o5 the varlety＂seven red＂ were also given in the report.
