１９８６～１９８８年用盆栽方法研究了夏大豆叶片蒸腾速率与叶位、叶龄、株龄及干物质积累的关系。结果表明；夏大豆蒸腾速率与各生育期叶龄、株龄及分枝期、始花期、结荚末期叶位的关系，及叶片蒸腾速率日变化均呈单峰曲线，都可用模式模拟．鼓粒中期、鼓粒末期的叶位及各生育时期植株干物质积累与蒸腾速率呈显著线性相关关系。
From 1986 to 1988, the relationship between leaf transpiration rate and leaf position, leaf age, plant age and dry matter accumulation of summer soybean was studied by pot culture method. The results showed that the relationship between transpiration rate of summer soybean and leaf age, branch age, branch stage, initial flowering stage and pod end stage and diurnal variation of leaf transpiration rate showed a single peak curve, which could be modeled. There was a significant linear correlation between leaf position at the middle stage of drum grain, dry matter accumulation and transpiration rate at the end of drum grain stage and each growth period.
