模拟酸雨对南方红豆杉生理特性的影响
Effect of Simulated Acid Rain on Physiological Characteristics in Taxus chinensis var. Mairei
摘要
Abstract
The test was conducted with 2—year—old trees of Taxus chinensis var. Mairei. Leaves were sprayed with the simulated acid rain with different pH values to study the effects of the acid rain on the physiological characteristics and leaf morphology in Taxus chinensis var. Mairei. The results indicated that blade tip appeared damage spots and leaf loss occurred under the stress of acid rain. There were not significant change of the content of chlorophyll and carotenoids and malondialdehyde and soluble sugar and protein. Superoxide dismutase activity did not change significantly under the acid rain stress. Compared to the control, catalase activity significantly increased with acid rain of pH4.0 and 5.6, decreased with acid rain of pH2.5. and peroxidase activity was significantly higher than those of control in pH5.6, and lower than those of control in pH4.0 and 2.5. Therefore, it has been showed a certain resistance to acid rain stress of Taxus chinensis var. Mairei. in pH4.0 and 5.6.关键词
