野生豆腐柴茎叶的解剖结构的初步研究(英文)

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

[目的]该研究为研究野生豆腐柴茎叶的解剖结构。[方法]运用植物解剖技术对豆腐柴的茎、叶作解剖观察。[结果]结果显示茎为辐射对称的轴器官,初生结构均有表皮、皮层、维管柱三大部分组成;叶柄由表皮、皮层和维管束构成;表皮一层细胞,外具角质膜和表皮毛;阳生叶为两面叶,叶片具栅栏组织与海绵组织,阴生叶几为等面叶。[结论]该研究结果为进一步开发利用野生豆腐柴资源提供了参考。

[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.
