摘　　要：应用光学显微镜和扫描电子显微镜,对悬铃木成熟球果及果毛的形态结构进行了观察。悬铃木成熟球果外部由小坚果及其基部的果毛组成,内部为头状花序的花托。球形花托表面有一层网状结构,其上着生小坚果及部分果毛,内部为花托的木质部分。果毛分为长直毛和齿状分枝毛,表面光滑,每根果毛都由若干个节组成,每个节为中空管状结构,管的外径约33μm,内径约23μm。果毛基部为短节组成的扁平管,中部为长节组成的圆形管,端部为尖刀状或分枝状。The structures of fruit and fruit fairs of the Platanus acerifolia were invested by the digital light microscope and the scanning electron microscope（SEM）. The surface of fruit is nuts and fruit hairs in the end of nuts. The inside of fruit is receptacle with exterior net structure that locates the nuts and some hairs and interior wooden structure. The fruit hair with smooth surface and several node-tube sections is divided into erect hair and branch hair. There are there different shapes along the fruit hair. the flat tube in the end; the circle tube with 33 m out-diameter and 23 m in-diameter in the middle; the knife-like or branch-like shape on the tip.
