【摘要】 [Objective]To study the microstructure of immature tuber,mature tuber and mother tuber of Gastrodia elata Bl.form.glauca S.Chow,and the powder of flower and stem for the first time.[Methods]Hand-sliced method,permanent paraffin-cut section and powder method were used to study the microscopic and powder characteristics.[Results]The microstructure of gastrodia was composed of lower epidermis,cortex and vascular cylinder.Immature tuber and mature tuber was the same,mother tuber was different from them in vascular bundle section.The corresponding structure of immature,mature and mother tuber cell increased gradually.There were nonglandular hair,spiral vessel,calcium oxalate raphides,secretory canal in powder characteristics of flower of G.elata Bl.f.glauca S.Chow,and there were epidermic cells,cork cells,calcium oxalate raphides and crystals with refracted light in powder characteristics of stem of G.elata Bl.f.glauca S.Chow.[Conclusions]These features can be used as the reference for quality standard of G.elata Bl.f.glauca S.Chow.
