中文摘要：运用石蜡切片和电镜扫描等方法对菠萝蜜叶和花进行解剖学的观察和研究,结果表明:菠萝蜜的叶是典型的异面叶;表皮细胞的角质层较厚,叶肉有2～4层栅栏组织,海绵组织细胞间隙发达,在叶肉和叶脉中还有较多含单宁的薄壁细胞,叶脉的木质部非常发达;说明了菠萝蜜的叶具有较强的耐旱和抗虫能力。花小,单性,花粉粒小而量多,风媒传粉;三孔花粉粒。

外文摘要：The leaf and flower of Jackfruit were anatomized by paraffin method and the anatomical structures of the leaf and flower of jackfruit were observed under optical microscope or scanning electron microscopy. The results showed that the leaf of jackfrnit is typical bifacial leaf, with relative thick horny layer of epidermis cell, 2 or 4-layer palisade tissue in mesophyll and more cell gap in spongy tissue. There are many tannin parenchyma cells between the mesophyll and the vein,and the xylem of the vein is highly developed. These results indicated that the leaf of jackfruit had relative strong drought tolerant and insect-resistant qualities. The jackfruit is propagated through anemophilous pollination,and its flower is unisexual and small,with tiny but rich pollen grains. The pollen grains are triaperturate.
