| 摘要: |
| 白车轴草花蜜腺位于雄蕊花丝的基部，属雄蕊蜜腺。蜜腺由分泌表皮和泌蜜组织构成，属于结构蜜腺。分泌表皮包括表皮细胞和气孔器，泌蜜组织细胞多层，花丝基部表皮及表皮内侧细胞恢复分裂能力形成蜜腺，在其发育过程中，液泡、淀粉、蛋白质发生有规律的变化。原蜜来源于花丝维管束，通过泌蜜组织加工成蜜汁，以后由气孔排出。 |

| A Study of the Development and Anatomy of Floral Nectaries in Trifolium repens |
|
|
| Abstract: |
| The floral nectaries of Trifolium repens L.are located on the base of filaments.They belong to staminal nectaries.The nectaries consist of epidermis and nectariferous tissue.They are structural nectaries.Many stomata scatter in the epidermis of the nectaries.The nectariferous tissue is composed of several layers of cells.The nectaries initiate from the superficial layer cells of the base of the filaments.During the development of nectaries,the starch,vacuole and protein change regularly.The pre nectar is provided by the vascular bundles of the base of the filaments.The nectar formed in nectariferous tissue is finally secreted by stomata. |
| Key words: Trifolium repens L.,floral nectary,development and anatomy |
