空中开花,入地结实的现象在植物界中是比较少的。除了花生(Arachis by-pogaea L.)外,还有Arachis属植物,该属在南美有许多种;豆科植物中的Voandzeia scabterranea原产非洲马达加斯加,俗名Bambarra groundnut,幼果也埋在地下,可食;北京西山有双籽两型豆(Amphicarpaea edgeworthii),其果实也是地下结荚的(吴征镒,1982)。从进化角度看,入地结荚对保存后代无疑是具有有利的生物学意义;从生产角度看,荚果形成直接关系到产量,掌握入地结荚机理并加以利用,就能提高植株荚数,增加产量。所以,花生入地结荚现象无论在理论上或实践上都值得研究。
Flowering in the sky, the phenomenon of strong ground into the plant world is relatively small. In addition to Arachis by-pogaea L., there are also Arachis, a species of which is found in South America. Voandzeia scabterranea is a native African Madagascar, commonly known as Bambarra groundnut, Food; Beijing Xishan double seed and two types of beans (Amphicarpaea edgeworthii), the fruit is also pod underground (Wu Zhengyi, 1982). From an evolutionary point of view, it is undoubtedly of great biological significance to conserve the offspring that the pod planting in the field has a favorable biological significance. From the perspective of production, the pod formation is directly related to the yield, Increase production. Therefore, the peanut pod into the ground both in theory or in practice are worth studying.
