摘　　要：采用一对叶型不同的姊妹系"辽99116"的尖叶型和圆叶型大豆品系,分别在盆栽和田间条件对不同叶型大豆品系的器官平衡与产量的关系进行比较研究。结果表明:无论在盆栽还是田间条件下,尖叶型大豆品系的器官平衡比圆叶型更趋于合理。尖叶型的经济系数在盆栽和田间条件下均高于圆叶型,但尖叶型大豆品系在田间栽培条件下的生物产量和籽粒产量却低于圆叶型,可能是试验的田间密度低于尖叶型的适宜密度所致。A comparative study that probes into the relationship between the organ balance and yield of soybeans with different leaflet type was carried out recently.A pair of soybean sister lines with narrow and broad leaflet,were planted in the potted and field conditions,the dry weight of leaf,petiole,stem,pod shell,seed and root were determined to seek the organ balance.Whether in the potted or field conditions,the organ balance of narrow lines was more reasonable than that of broad ones.The economic coefficients for narrow soybeans were higher than those of broad ones in both potted and field conditions,but the biological yield and seed yield of former were lower than those of latter in field conditions,maybe the test population was not enough for the narrow leaflet soybean.
