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。
With the leaf area of Gladiolus measured by digital camera and Photoshop software as a referquation 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.
