摘要： 从显微水平及亚显微水平研究了锌处理对植物细胞毒性的影响。实验结果表明，不同浓度的锌对植物根端细胞的损伤不甚显着，细胞内主要细胞器结构完整，液泡呈轻至中度凝集，微核形成率很低。

Abstract: In this paper the influence of zinc on toxicity to some plants was studied at the level of microstructure and submicrostructure. The results indicated that damage to plant root-tip cells was not remarkable after treatment with different concentration zinc. The structures of main organelle within cells had been preserved intact. The frequency of micronucleated cells was very low. But the vacuole appeared to be condensed at low to middle degree.
