摘要: 植物对SO2气体的敏感性是由多种因素相互作用而形成的复杂综合性状,常用于定性描述大气环境质量状况。通过在密闭的培养瓶中一次性通入不同体积浓度的SO2气体,以不同浓度SO2胁迫下的不同类型植物为例,观察其在不同时间的外观伤害症状和细胞膜透性。结果表明:不同植物对SO2的敏感性不同;低浓度长时间和高浓度短时间的症状基本相同;植物细胞膜透性数据即电导率直接反映植物受损程度。综合植物外观症状指标与生理生化指标并赋予不同权重值,建立了相对定量化的大气质量生物学指标评价模式,以定量判断SO2气体对植物的伤害,为应用植物监测和评价大气环境质量提供了依据。

Abstract: The sensitivity of plant to SO2 is a complicated and comprehensive character formed by the interactions of many factors, and often used to qualitatively describe air environmental quality. In this paper, the leaf appearance symptoms of plants exposed to different concentration SO2 were observed. The results showed that different plants had different sensitivity to SO2. The symptoms of plants exposed to low SO2 concentration for a long time were similar with those exposed to high SO2 concentration for a short time. The cell membrane permeability (electrical conductivity) of plants could directly reflect the damaged degree of plants. Based on the integrated data of plant appearance symptoms and physiological/biochemical indicators, a quantitative bio-evaluation model of air quality was established, which provided a basis for monitoring and evaluating atmospheric environment by plants.
