摘　　要：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。Objective To provide basis for identification and utilization of Phytolacca decandra. Methods Anatomic structures of different-aged storing roots, stems and leaves of P. decandra were studied by light microscope and histochemical localization. Results Different-aged vegetative organs have active proteins except the young roots, and the protein used to exist in parenchyma cells. Conclusion Protein content in young stems is the highest and the grain size is bigger than the other organs, and the protein content and grain size in young stems have notable differences from that in the old leaves, young leaves, old stems and roots. No protein has been found in two-year-old storing roots and extra cambium.
