本试验是研究人工(模拟)酸雨对番茄果实及枝叶生长的影响.用配制成pH值为4.5、3.5、3.0和2.0的系列酸水对番茄植株进行喷洒处理。试验结果表明,人工酸雨对番茄植株中后期生长(果实重量和新生枝长度)的影响不太明显,对叶片和果实的某些生理特性指标(pH值、细胞透性)的影响比较显著.在本试验条件下,番茄植株对酸雨的敏感性同青菜和莴苣相比是不敏感的.
This experiment is to study the effects of artificial (simulated) acid rain on the growth of tomato fruits and leaves. Tomato plants were sprayed with a series of sour water formulated at pH 4.5, 3.5, 3.0 and 2.0. The results showed that the effect of artificial acid rain on tomato growth and later growth (fruit weight and new branch length) was not obvious, and had significant effects on some physiological characteristics (pH and cell permeability) of leaves and fruits. Under the experimental conditions, the sensitivity of tomato plants to acid rain is insensitive to vegetables and lettuce.
