本文研究了两个番茄品种(“白果”,“丽泰”)在营养生长阶段,植株地上部分千重、叶干重与叶面积的相关性。结果表明:叶面积与叶干重比值(两品种平均)基本不变;植株地上部分干重、叶干重与叶面积均呈极显著正相关,其相关系数分别为R=0.9845和R=0.9967,提出了用植株地上部分干重和叶干重估测叶面积的一元线性回归方程式。
In this paper, we studied the correlation between leaf weight and dry weight of two tomato cultivars (“Ginkgo” and “Ritai”) during vegetative growth stage. The results showed that leaf area to leaf dry weight ratio (average of two cultivars) remained basically unchanged. The dry weight of aboveground parts, leaf dry weight and leaf area were significantly and positively correlated with the correlation coefficients R = 0.9845 and R = 0.9967 , A simple linear regression equation was proposed to estimate the leaf area based on dry weight of the aerial part of the plant and leaf dry weight.
