摘要: 以数码相机结合Photoshop软件实测的唐菖蒲(Gladiolus hybridus Hort)叶面积为参照,用不同叶位叶片的长径(L)和宽径(W)求得唐菖蒲叶面积的矫正系数和回归方程。以矫正系数(K)法求算叶面积:品种“桃红”LA=0.65LW,品种“玫瑰粉”LA=0.71LW;回归方程法求算叶面积:“桃红”LA=0.58×L×W+ 7.02,“玫瑰粉”LA=0.69×L×W+ 1.58。经方差分析比较证明,应用回归方程法计算的叶面积比用矫正系数法更为可靠。

Abstract: With the leaf area of Gladiolus measured by digital camera and Photoshop software as a reference, the correction coefficient and regression equation were gained by calculating long diameters (L) and short diameters (W) of Gladiolus leaves. According to the method of leaf area correction coefficient, the equation for both red-peach and pink-rose were LA=0.65LW and LA=0.71LW, respectively. The regression equation of red-peach and pink-rose were LA=0.58×L×W+ 7.02 and LA=0.69×L×W+ 1.58, respectively. The result of variance analysis revealed that regression equation method could give a more reliable result than Leaf area correction coefficient method for the leaf area measurement.
