番茄叶不规则,厚薄不均,用常规方法测定其叶面积的准确性不高.本文以白果和丽泰番茄品种为试材,探讨植株干重和叶面积的关系.在2片真叶展至开花.5天随机取3钵去掉根系,将叶片铺平于纸上描绘其形状,再将叶与茎分别放入称量皿中,置于60℃烘箱中烘至恒重称量.叶面积(cm~2)=叶纸样重(g)×单位叶面积纸样重的倒数(cm~2/g),植株干重=叶干重+基干重.1 叶面积与叶干重的关系随着植株生长。叶面积(y)与叶干重(X)均同步增加.其回归方程为:
Tomato leaf irregular, uneven thickness, using conventional methods to determine its leaf area accuracy is not high.This paper gingko and Litai tomato varieties as the test material to explore the relationship between plant dry weight and leaf area in two true leaf exhibition 5 days to take 3 bowls to remove the roots randomly, flatten the leaves on the paper to depict the shape, and then leaves and stems were placed in a weighing dish, placed in a constant temperature oven at 60 ℃ to weigh. Area (cm ~ 2) = Leaf-like weight (g) × Leaf weight per unit area (cm ~ 2 / g), Dry weight of plant = Leaf dry weight + Basal weight. Plant growth. Leaf area (y) and leaf dry weight (x) both increased synchronously.The regression equation was:
