Developmental Anatomy of Floral Nectary in Thymus marschallianus Wiild
摘要
Abstract
The floral nectary of Thymus marschallianus Willd is located on the base of ovary receptacle, disk-like , which inflated after mature and surrounded around the receptacle. The top of the floral nectary is divided into 4 same size slices. The nectary is composed of epidermis, nectariferous tissue and vascular bundles. Histo-chemistry staining showed that the starch grains were accumulated in the beginning and the later stages of nectary development, so the nectary belonged to non-starch nectary. During the development of nectary, the morphological changes of vacuoles are obvious, but the changes of starch grains and polysaccharide are not obvious. It is suggested that the nectar is transported from phloem to nectariferous tissue and then excreted by permeation through the thin cuticle of epidermis.关键词
