摘　　要： 为了解菠萝蜜（Artocarpus heterophyllus Lam.）果肉的发育过程,运用石蜡切片和水装片的方法对其进行解剖学观察.结果表明,菠萝蜜果肉由表皮、基本组织和维管束组成,花后8 周表皮和基本组织细胞中出现淀粉粒,成熟时完全消失,贮藏作用明显;外表皮细胞形态较规则,而内表皮细胞壁的初生纹孔场相对较多;维管束不发达,发育过程中没有明显变化.菠萝蜜果实发育成熟在花后18-19 周.这为菠萝蜜的解剖学基础研究积累了资料. In order to understand the development of jackfruit(Artocarpus heterophyllus Lam.) pulps, the anatomical structure of its pulps during development was observed under light microscope by using water slice and paraffin section. The results showed that jackfruit pulp consisted of epidermis, basis tissues and vascular bundles. Starch grains appeared in epidermis and basis tissues at 8 weeks after flowering and then degraded at mature stage, showing obvious storage function. The shape of outer epidermis cells are regular, and cell wall of inner epidermis cell has more primary pit fields than that of outer epidermis cells. The vascular bundles in pulp are undeveloped, and there is no significant change throughout development process. The mature of jackfruit pulps was at 18 to 19 weeks after flowering. These accumulate materials for anatomical studies of jackfruits.
