本研究结果表明,大豆不同类型品种的粒茎比差异转大,粒茎比的大小与品种的生育期长短、植株高度、叶面积指数、粒茎产量呈高度显著或显著的负相关。与叶片形状的关系亦相当密切,长叶类型品种粒茎比高于园叶类型品种。粒茎比与籽粒大小无关,与籽实产量呈不显著的正相关。就粒茎比、株高、籽实产最三者关系而言,以株高80—90厘米粒茎比平均在1.7以上的品种类型籽实产量最高。
The results of this study showed that the differences of grain-stem ratio of different varieties of soybean were enlarged, and the grain-stem ratio had a highly significant or significant negative correlation with the growth duration, plant height, leaf area index and grain stem yield. The shape of the leaves is also very closely related to the long-leaf type varieties than stems and leaves of varieties. Stem-grain ratio had nothing to do with the grain size, and seed yield was no significant positive correlation. In terms of grain stem ratio, plant height, seed production of the top three relations, with 80-90 cm stem diameter than the average 1.7 or more varieties of seed yield is highest.
