西瓜的叶面积可以通过叶宽来进行快速估计,以蜜宝和华东24号两个品种为试验材料,测得的叶宽与叶面积的相关系数分别为0.9273和0.9717, 均达到1％显著水准。其直线回归方程式为 Y=-58.9869+12.2577x(蜜宝品种)、Y=-66. 9084+13.5831x(华东24号品种)。 采用曲线方程配合Y=ax~b比logy=a+bx效果为好。这在实际检验中,也都得到了证实,其最佳方程是Y=2.2843x~(1·4232)(蜜宝品种)和Y=1.0179x~(1.7871)(华东24号)。 这种估计叶面积的方法具有方法简便,不必破坏叶样,具有一定正确性。文后附有参考表。
The leaf area of watermelon can be quickly estimated by leaf width. The correlation coefficient between leaf width and leaf area was 0.9273 and 0.9717, both of which were significantly higher than 1% . The linear regression equation for the Y = -58.9869 +12.2577x (Mi Bao varieties), Y = -66. 9084 +13.5831x (East 24 varieties). Using curve equation with Y = ax ~ b than logy = a + bx effect is better. In the actual test, it has also been confirmed that the optimal equation is Y = 2.2843x ~ (1.4232) (MiBao varieties) and Y = 1.0179x ~ (1.7871) (East China 24). This method of estimating the leaf area has the advantages of simple method and no need to damage the leaf sample, and has certain accuracy. Text attached to the reference table.
