A Preliminary Study on Anatomy of the Stem and Leaf of Premna microphylla Turcz.

Objective] This study was to reveal the anatomic structure of Premna microphylla Turcz.stem and leaf.Method] Using plant anatomy method,we performed anatomic analysis of Premna microphylla Turcz.stem and leaf.Result] The stem of Premna microphylla Turcz.is axially symmetric organ,its primary structure consists of three parts of epidermis,cortex and vascular cylinder.The petiole consists of epidermis,cortex and vascular cylinder,of which epidermis is a layer of cells with cuticle and epidermal hair.The sun leaf in Premna microphylla is dorsi-ventral leaf,wich is consist of palisade tissue and spongy tissue;while its shade leaf of Premna microphylla almost are isobilateral leaf.Conclusion] Our results provided reference for further the exploitation and utilization of Premna microphylla Turcz.resources.
