| 摘要: |
| 以浸水处理为对照系统分析了Fe2+、Cu2+、Zn2+等金属离子对植物胁迫损伤相关的7个生理指标,并应用数理统计学和生物化学的相关原理和方法从氧自由基伤害的角度比较分析了这三种离子处理对植物生理特性的影响。结果表明:不同离子处理由于对植物造成的胁迫损伤不同,因而它们对植物生理特性的影响效应也有明显差异,并且这种差异与其所处理的离子胁迫性质间存在显著的关联性。 |

| Abstract: |
| This paper studied on seven physiological indices,which had correlation with stress effect of Fe2+,Cu2+and Zn2+ to plant when the treatment of soaking in water as control. Meanwhile,the principle and method of biochemistry and biostatistics were applied. The effect of three ions treatments to plant physiological characteristics was analyzed according to damage of oxygen free radicals. The results were as follows:the effect of physiological characteristics had evidently difference because different ion treatments had different stress damage. And the difference had marked correlation with ion stress character treated. |
