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。
The relationship between organ balance and yield of different leaf type soybean lines under pot and field conditions was studied by using a pair of sharp-leafed and round-leafed soybean lines with different leaf types and sister lines of “Liaoning 99116”. The results showed that the organ balance of sharp-leafed soybean lines tended to be more reasonable than that of the round leaves, both in potted and field conditions. The economic coefficient of sharp-leafed type was higher than that of round-leafed type under both potted and field conditions, but the yield and grain yield of sharp-leafed soybean was lower than that of round-leafed under field cultivation, which may be due to the low field density Due to the appropriate density of pointed leaves.
