摘　　要：目的:通过对通城移植毛喉鞘蕊花进行系统形态解剖学研究,以期改善种植条件,提高种植毛喉鞘蕊花的品质。方法:采用常规石蜡切片,番红固绿双染制片法,光学显微镜观察根、茎、叶及其茎下部膨大部分的内部构造。结果:通城移植毛喉鞘蕊花根的次生构造的维管组织较发达;茎的皮层和髓部所占比例较大,含4个较大的维管束,随着植物的生长维管组织更发达;叶片表皮细胞有丰富的腺毛、腺鳞和线状非腺毛等毛茸,叶肉细胞分化不明显;茎下部膨大部分具有双子叶植物根茎构造的特点。结论:通城栽培毛喉鞘蕊花呈现出茎下部膨大的根茎,根茎下方不明显的肉质根及叶肉细胞分化不明显等特征。本项研究为药材质量标准制订、栽培及其药材资源应用提供了参考依据。Objective：To investigate the vegetative tissues of Coleus forskohlii cultivated in Tongcheng, Hubei Province,and to pro- vide useful information for its planting. Methods：The root, stem, leaf and enlarged rhizome of Coleus forskohlii were subject to routine paraffin section and staining with safranin and fast green FCF solution before examination by light microscopy. Results：The secondary tissue was well developed in root, and stem showed a higher percentage of cortex and pitch, and 4 large vascular bundles. Leaf epidermis was covered by lots of trichomes,including glandular hairs, glandular scale and linear non-glandular hairs. Mesophyll tissue was poorly differentiated to palisade and spongy tissues. Enlarged rhizome was the same as normal dicotyledons plants. Conclusion：Enlarged rhizo- me, unconspicuous root tuber and poorly differentiated leaf mesophyll cells are 3 main different features of Coleus forskohlii transplanted in Tongcheng. These results provide scientific basis for formulating quality standards, further cultivation and utilization of the plant.
