玉竹的生物学特性及解剖学观察

Biological Characteristics and Anatomical Observation of Polygonatum odoratum

通过对玉竹的观察研究,初步明确了玉竹的形态特征、生态习性、生长发育规律、繁殖特点及孢粉学等特征、特性。解剖学观察表明,根由表皮、皮层和维管柱组成,根状茎及茎由表皮、皮层、基本组织和维管束组成,茎的皮层内还具有环状的机械组织。

The morphological features, ecological habits, hales of growth and development, characteristics of reproduction and palynology of Polygonatum odoratum were clarified through observation and studying. Anatomical observations showed that the roots were composed of the epidermis, cortex and vascular cylinder; the rhizome and stem were consisted of the epidermis, cortex, elementary tissue and vascular bundle.
