大豆不同结荚习性各方面表现的内在联系的差异,即其本质区别,是主茎顶端花芽分化期的个体发育年令不同。大豆结荚习性是在个体发育阶段不同的基础上形成的一种数量性状。这方面的量变达到一定程度后,便使品种特性发生质变,从而形成生产上结荚习性不同的三种生态类型。有一类结荚习性是在营养生长和生殖生长这二个发育阶段交错程度不同的基础上产生的。另一类是在开花和结荚这二个发育阶段的交错程度不同的基础上产生的。在本文中,称前一类为“甲类结荚习性”;后一类为“乙类结荚习性”。结荚习性可按一株的顶叶与最大叶的中间小叶的“长+宽”的比值分为十一级。0至4级为无限性;5至8级为亚有限性;9至10级为有限性。
Soybean pods different aspects of the performance of the inherent relationship between the differences, that is, the essential difference is the main stem flower bud differentiation at the top of the individual development of different years. Soybean pod habit is a quantitative trait formed on the basis of different stages of development. After the quantitative change in this area reaches a certain level, the variety characteristics will be changed qualitatively to form three ecological types with different pod habit. One type of pod habit arises on the basis of different degrees of interlacing at vegetative and reproductive growth stages. The other is produced on the basis of the different degree of interlacing between the two developmental stages of flowering and podding. In this article, we refer to the former as “Group A” and “The latter” as “Group B”. Podding habits can be a strain of the parietal lobe and the largest leaf of the middle of the “long + wide” ratio is divided into eleven. Levels 0 to 4 are infinite; levels 5 to 8 are sub-finite; and scales 9 to 10 are finite.
