Abstract：In order to understand the anther wall structure and pollen developmental features of Cucumis melo,anthers of different developmental stages were observed by microscopy.The meiosis of the microspore mother cell gave rise to four microspores,which were arranged in a tetrahedroid pattern within a common callose wall.Mature pollen grains,which were 45 μm in diameter,contained numerous lipid droplets and therefore belonged to lipidic type.The anther wall was comprised of epidermis,endothecium,middle layer and tapetum,each consisting of a single celled layer.The tapetal cell was degenerated on its original location and so the tapetum belonged to glandular type.The epidermis developed a lot of single celled trichomes.The trichome cell was enlarged and contained rich cytoplasm and survived until the pollen grains got mature.
