To clarify the role of raceme order on podding of soybeans, field experiments were conducted 1992 to 1994. The yield was correlated with No.of podds among the plots of different planting densities. The No.of podds showed clear positive correlation with the No.of flowers, but no relationship with podding ratio.The No.of flowers per phytomer was influenced by the No.of flowers per raceme in lower raceme order, the No.of racemes per phytomer in higher raceme order, respectively.It was suggested that the increasing yield of soybean relates to the increasing the No.flowers per unit area which consists of the No.of flowers per raceme and the No.of racemes per phytomer. The No.of flowers per raceme is recognized to vary before the flowering stage, on the other hand the No.of racemes per phytomer is limited after the stage.

为了阐明总状花序在大豆结荚中的作用，1992-1994年进行了田间试验。不同种植密度小区的产量与角果数呈显著正相关。结荚数与结实率呈显著正相关，但与结荚比无显著相关，总状花序下位花序花数和总状花序高位总状花序花序数分别影响大豆单株花数，说明大豆增产与增加单位面积花数有关，单位面积花数由总状花序花数和总状花序数组成。每个总状花序的花数在开花期之前是变化的，而在开花期之后每个植物的总状花序的数目是有限的。
