目的为商陆的开发和利用提供依据。方法利用光学显微技术、组织化学定位方法对美洲商陆Phytolacca decandra不同生长龄的根、茎和叶进行解剖结构研究。结果除幼根外,不同生长龄的营养器官中均有活性蛋白质分布,薄壁细胞是活性蛋白质分布的场所。结论幼茎中蛋白质的量最为丰富,颗粒也较大,与老叶、幼叶、老茎和老根中蛋白质的数量及大小差异极显著;二年生的贮藏根中不含蛋白质,额外形成层中几乎不含蛋白质。
The purpose is to provide a basis for the development and use of commercial land. METHODS: The anatomical structures of roots, stems and leaves of Phytolacca decandra from different ages were studied by optical microscopy and histochemical localization methods. Results Except for juvenile roots, active protein distribution was found in vegetative organs of different growth ages, and parenchyma cells were sites of active protein distribution. Conclusion The amount of protein in juvenile stems is the most abundant and the number of particles is larger. There is a significant difference in the number and size of proteins in old leaves, young leaves, old stems, and old roots. The storage roots of biennials do not contain protein, and extra layers are formed. Almost no protein.
