摘    要:唐古特白刺(Nitraria tangutorum Bobr.)蜜腺位于花瓣内侧,按Fahn蜜腺分类法,属花被蜜腺;其由分泌表皮细胞构成,从植物解剖学的角度来看,又属典型的非结构蜜腺;经组织化学染色显示,淀粉粒的动态不明显,因此又属非淀粉蜜腺。唐古特白刺的分泌表皮细胞,在蜜腺发育过程中特化为分泌表皮毛,分泌腔原始细胞在蜜腺发育过程中裂解成分泌腔,分泌表皮上具有特殊的角质层纹理,在分泌表皮细胞发育过程中,液泡呈现一定的变化规律,其变化与蜜汁的合成和分泌规律相关,液泡是参与了多糖物质的降解、蜜汁的转运等物质的循环而发生着有规律的变化,淀粉和糖原的动态不明显。最后形成的蜜汁经分泌腔,由分泌表皮细胞特化为单细胞的表皮毛中泌出,在败花期时,分泌表皮毛萎缩并随花瓣一起脱落,泌蜜由此停止。

关 键 词:唐古特白刺  花蜜腺  发育解剖学  组织化学

Abstract:Nitraria tangutorum Bobrov nectary is located in the inner petal,and it is composed of secretive epidermal cells.According to Fahn classification of nectary,it belongs to the typical perianth nectary,it is also the typical non-structure nectary based on the plant anatomy.It belongs to the non-starch nectary because starch dynamic is not obvious during dying.The secretive epidermal cells are specialized to secretive trichomes,and the secretory cavity is formed by the split of the original secretive cells dur...
Keywords:Nitraria tangutorum  floral nectary  developmental anatomy  histochemistry
