| 摘 要： | 蒲公英的花蜜腺位于花柱基部，呈筒状围绕花柱，新鲜时呈绿色，属于花柱蜜腺。其结构由分泌表皮和泌蜜组织组成，不含有维管束。分泌表皮上有气孔分布，孔下室发达，泌蜜组织的内侧与花柱维管束相邻。蜜腺由花柱基部的细胞发育而来，在蜜腺发育的过程中，其细胞结构和贮藏都发生了规律性的变化。原蜜汁由花柱基部的维管束提供，经过泌蜜组织细胞加工成蜜汁后，通过气孔排出体外。

| Abstract: | Taraxacum mongolicum has a green tubular stylar nectary located at the base of the style.The nectary,which lacks special vascular bundle,is composed of secretory epidermis and nectariferous tissue.Stomata are present in the epidermis and they have well developed space under them.The nectary initiates from the superficial layer cells of the base of the style.During the development of nectary,the structure and content of cells change regularly.Pre nectar is provided by the vascular bundle of the base of the style.Nectar formed in nectariferous tissue is secreted by the stomata. |
