改变普通大豆生物学特性提高大豆产量的研究Ⅰ.扁茎大豆的生物学特性

CHANGING BIOLOGICALLY SPECIFIC CHARACTERISTIC OF COMMON SOYBEAN VARIETY TO INCREASE SEED YIELD OF SOYBEAN Ⅰ.BIOLOGICAL CHARACTERISTIC OF FASCIATED SOYBEAN

与普通大豆品种相比较，扁茎大豆植株较矮，节间短；节数不多，但叶数多；叶片着生奇特；叶片较小，叶柄较短；顶端花序特长，开花结荚密集。

Fasciated soybean had shorter plant hight and length of inter nodes, more leaves per plant, less area per leaf, shorter petiole than common soybean varieties. Number of node on main stem of fasciated soybean was similar to common varieties. The soybean has very long top inflorescence and flowers and pods crowded together on the inflorescence. Fasciated soybean was easy to lodge.
