以 3种不同结荚习性大豆为材料 ,研究了大豆顶节位叶面积与籽粒重之间的关系 ;单株各节位叶面积大小与同节位籽粒重之间的关系。结果表明 ,大豆顶节位叶面积与籽粒重之间呈极显著的正相关关系 ,相关系数r =0 .893 ;单株各节位叶面积大小与籽粒重之间呈显著的正相关关系 ,相关系数r=0 .663 (有限 )、r=0 .5 2 6 (亚有限 )、r=0 .878 (无限 )。
The relationship between the top leaf area and the grain weight of soybean was studied using three different pods of soybean. The relationship between the leaf area per plant and the grain weight at the same node was studied. The results showed that there was a significant positive correlation between the top leaf area and the grain weight of soybean, the correlation coefficient was 0.893. There was a significant positive correlation between the leaf area per plant and the grain weight, The correlation coefficient r = 0.663 (finite), r = 0.5256 (sub-finite), r = 0.788 (infinity).
