摘　　要：艾比湖沙拐枣植物的花蜜腺位于花丝基部并延续到花托,属于花托/雄蕊蜜腺,蜜腺由分泌表皮、产蜜组织和维管束组成。在花的发育过程中,蜜腺由本身的原始细胞分裂、分化而来;其花蜜腺在发育过程中液泡化动态明显,PAS反应测试细胞具阳性物质。泌蜜方式为:蜜汁由特化的表皮毛分泌到植物体外;其可能的泌蜜机理为:前蜜汁由产蜜组织合成,经特化的分泌表皮毛泌出。The flower nectaries of Calligonum ebi-nuricum Ivanova are located at the base of stamens and stretch to receptacles, which are also called Stamens nectary. The Nectary is composed of secretion epiderm, melliferous organization and vascular bundle. In the process of flower development, the nectary split up or differentiates from their original cells. And during the ontogenetic process, the floral nectary shows a vacuolization dynamics from what can be seen or known. The PAS reaction tests that the cells are filled with positive materials. The way of Nectar secretion is that the honey is secreted to plants in vitro by the specialized trichomes. And its possible nectariferous mechanism is that the honey is made up of melliferous organization and secretes through a specialized secretory trichomes.
