摘要(Abstract):

目的:鉴别毛叶木姜子和红叶木姜子果实的性状特征和显微特征。方法:采用性状鉴定方法比较研究毛叶木姜子和红叶木姜子果实的外观形态特征,采用切片、粉末制片等方法比较毛叶木姜子和红叶木姜子果实的横切面及粉末显微特性。结果:毛叶木姜子和红叶木姜子果实性状特征相似,外表面、果皮和子叶等存在差异;毛叶木姜子中果皮和内果皮细胞周围可见大量的草酸钙方晶,表面观内果皮细胞之间界限不清晰,层纹不明显,有的可见孔沟;红叶木姜子外果皮含有红棕色物质,表面观内果皮细胞垂周壁波状弯曲,层纹明显,油细胞含有黄色或棕黄色分泌物。结论:毛叶木姜子和红叶木姜子果实的性状特征和显微鉴别特征能为木姜子的分类和鉴别提供参考依据。
Objective: To study on the macroscopic and microscopic characteristics of fruits of Litsea mollis and Litsea rubescens. Methods: The morphological features of fruits of L.mollis and L. rubescens were observed by character identification methods. The microscopic characteristics of transverse section and powder of the fruits were studied by microscope. Results: The morphological characteristics of fruits of L. mollis and L.rubescens was similar, but there were differences in the surface, peel and cotyledon. A lot of prisms of calcium oxalate were found around the mesocarp and endocarp cells of L. mollis. The boundary between the endocarp cells and laminated striation in endocarp cells of L.mollis was not obvious, and some of them had pore grooves. The outer pericarp of L.rubescens contained reddish-brown substance, and the circumferential walls of endocarp cells were undulated with obvious lamination, and the oil cells contained yellow or brown-yellow secretion. Conclusion: The macroscopic and microscopic characteristics could be applied for the classification and identification of L.mollis and L.rubescens fruits to provide scientific evidence for the quality control of L.mollis and L.rubescens.
