Diversity in leaf shape is produced by alterations of the margin: for example, deep dissection leads to leaflet formation and less-pronounced incision results in serrations or lobes.

植物的叶子即可以是一个简单的叶片，也可以由多个单独的小叶组成。此外，无论单叶还是复叶都可能具有齿状或圆突状的边缘。

In order to make a further illumination of the inter-relationship of photoperiod and temperature in soybean growth and development, soybean cv.
