云南龙竹,黔竹的果实——一种植物学上新的果实类型

云南龙竹、黔竹的果实甚为特殊，可称之为两型果，它是在我们研究竹类植物果实长达２０余年的过程中新发现的果实类型，成熟的两型果上部果皮厚而坚硬、圆滚而有光泽，极近于栎属的假坚果，而其下部果皮薄软、不具光泽，颜色深灰且因它在成熟过程中水分的散失而皱缩，与竹类植物中的某些浆果雷同。

THE NEW TYPE OF FRUIT IN BOTANY

The fruit of bamboo is formed in a very long period of systematic evolution.It is very suitable for study the systematic classification and evolution of bamboo.We have studied the fruit of hamboo for about twenty years.The dimorphocarpy is our new find in the bamboo's fruit.The fruitwalls of the mature one is thick,hard,round and lustrous, similar to the spurious fruit-walls of Quercus(Fngaceae).The underneath of fruit-walls of dimorphocarpy is soft,in the process of its maturation,the moisture content evaporated caused the fruit-walls wrinkly.It's similar to the fruitwalls of baca.
