Developmental Anatomy of the Floral Nectaries in Salvia deserta Schang
摘要
Abstract
The floral nectary of Salvia deserta Schang from Xinjiang locates on the based ovary receptacle, which belongs to plate receptacle nectary. The top of the floral nectary is divided into 4 slices which differ in size distinctly. The nectary is composed of epidermis and nectariferous tissue belonging to structural nectary. Histochemistry staining shows obvious changes of starch grains,so the nectary also belongs to starch nectary. During the nectary development , there are obvious morphological changes of vacuole and obvious changes of starch grains and protein as well. However,no significant change of PAS reaction and Hematoxylin staining of lipids was observed. The pre-nec-tar comes from the adjacent phloem and then transports to nectariferous tissue by parenchyma cells. The nectar is gathered and synthesized in nectariferous tissue and is excreted from the epidermal cells and modified stoma at last.关键词
