摘要
综述了重金属锌对植物的毒害及机理方面的研究。其中包括锌对植物细胞超微结构、质膜透性、水分代谢、矿质营养、光合作用、呼吸作用、氮素代谢、核酸代谢、激素等生理生化过程,以及对植物生长发育的毒害效应。在毒害机理中讨论了植物体内原有的离子平衡系统,大分子物质活性和自由基与伤害的关系。并对该研究领域今后的研究方向进行了展望。
The literature on the toxicity of zinc to plants and its mechanism were reviewed. Toxicity of zinc to plants and its mechanism involved the toxicity of zinc on uhrastrueture of plant cell, plasmlema permeability, water metabolism, mineral nutrition, photosynthesis, respiration, nitrogen metabolism, nucleic metabolism, phytohormone, as well as growth and development of plant. As for toxicological mechanism, the relationship among ionic balance system, the activity of some macromotecues and free radicals in plants and injurv was discussed. And the future directions of research in this field were predicted.
