5种华南沿海湿地植物对人工含盐污水的生理响应
Physiological Responses of Five South China Coastal Wetland Plants to Artificial Saline Wastewater
摘要
Abstract
[Objective] The aim of this study was to determine the effects of artificial saline wastewater on the physiological responses of five South China coastal wetland plants and to analyze the differences in their tolerances under wastewater stress, [ Method] The seedlings of five wetland plants were planted in pots, and then watered respectively by the artificial saline wastewater with different concentrations, namely NW (one time) , FW (five times) and TW (ten times) every 15 days. And then the chlorophyll content, SOD, POD, MDA and free proline content in test plants were determined, and the physiological response of these plants to water body pollutants was compared. [Result] Kandelia candel and Laguncularia racemosa had the strongest tolerance to water pollutants, which could maintain normal growth in the ten times concentration wastewater (with a salinity of 20‰). Phragmites communis and Cyperus malaccensis var. brevifolius showed the weakest tolerance to water pollutants, which could only maintain normal growth in the one time concentration wastewater ( with a salinity of 10‰). Aegkeras cornic-ulatum was the medium one in tolerance, which was suitable to be grown in the 1 times and 5 times concentration wastewater (with salinity range of 10‰-20‰). The ability of pollution resistance from high to low was K. candel > L. racemosa > A. corniculatum > P. communis > C. malaccensis. [Conclusion] K. candel and L. racemosa could be used as the alternative plant materials for South China coastal wetland restoration.关键词
