摘要: 沙枣的花蜜腺位于花柱基部的筒状花盘上,属花盘蜜腺,其蜜腺位于花盘外方,由分泌表皮和产蜜组织组成。分泌表皮具有角质层和变态的气孔器。产蜜组织在发育过程中,其液泡和淀粉粒都随着蜜腺的发育呈现一定的消长规律,最后形成的蜜汁由盘状蜜腺表面的气孔泌出。

Abstract: Anatomic studies and cytological observation of the floral nectary in Elaeagnus angustifolia L.were investigated with light and scanning electron microscopy, Elaeagnus angustifolia of floral nectary located on the tubular disc in the base of the style, it belongs to disc nectary.The nectary located on the outside of the disc, which is composed of epidermis and nectariferous tissue.The cuticula and modified stomata are present in the epidermal layer.During the development of nectariferous tissue, both the vacuole and the starch grains occurred regularly decrease and increase change.Finally, the nectar secreted from the stoma on the surface of the disc nectary.
