摘　　要：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。Relationship between transpiration rate and leaf position,leaf age,plant age and accumulation of dry matter in summer soybean were studied with the method of pot culture in 1986～1988.The results showed that the diurnal changes of leaf transpiration rate and its relation to leafage,piant age in each growth stage and leaf position in branch stage,initial flowering stage andpod setting last stage were described with single peak curve and were simulated with model y=ax￣pe￣(bx).The linear correlation between transpiration rate and accumulation of dry matter in eachgrowth stage and leaf position in seed filling atage were significant.
