桃仁的显微鉴别

Microscopic Identification of Peach Seed

目的:对桃和山桃的干燥成熟种子进行显微鉴别。方法:采用显微鉴别的方法对桃仁、山桃仁的组织和粉末特征进行研究。结果:组织切片中桃仁的种皮细胞外侧含有大量石细胞、内胚乳细胞层较窄;粉末中含有种皮表皮细胞、子叶细胞、导管细胞等特征。结论:桃仁的石细胞、种皮表皮细胞、内胚乳及子叶细胞、导管细胞、糊粉粒均可作为鉴别特征,为桃仁的鉴别、质量评价及开发利用提供科学依据。

Objective：To identify the microscopic identification of dry mature seeds of Prunus persica（L.） Batsch and Prunus davidiana（Carr.） Franch.Method：Research the features of tissue and powder of P.persica and P.davidiana using the method of microscopic identification.Result：In tissue slices of peach seed,the seed coat cell lateral contains a lot of stone cells,the endosperm cell layer is relatively narrow;In powder slices there contains some features about the epidermal cells of seed coat,cotyledons cells,catheter cell and so on.Conclusion：The stone cells,the epidermal cells of seed coat,the endosperm and the cotyledons cells,the catheter cells,the aleuronic grain could be used as identification characters through the research.Provide scientific basis for the identification,quality evaluation,development and utilization of the peach seed.
