中文摘要	为探究藜科植物在重金属胁迫下的生理响应以及其耐受性,以藜科荒漠植物四翅滨藜(Atriplex canescens (Pursh) Nutt)、盐爪爪(Kalidium foliatum (Pall) Moq)和碱蓬(Suaeda glauca (Bunge) Bunge)为研究对象,采用盆栽试验,通过设置不同的土质背景(EG0, EG1和EG2),测定植物的生理生化指标,并运用灰色关联度分析、主成分分析、隶属函数方法综合评价3种藜科植物对重金属的耐受性。结果表明:EG1处理造成3种植物的丙二醛和可溶性蛋白含量上升,游离脯氨酸含量下降;过氧化氢酶和超氧化物歧化酶的活性均显著降低;过氧化物酶活性出现了不同程度的增强,但经EG2处理后的四翅滨藜的过氧化物酶活性显著降低。主成分分析法在8个生理指标中筛选出3个主成分,他们分别是MDA因子、Pro因子和SOD因子。相关分析结果表明还原型谷胱甘肽含量与过氧化氢酶和超氧化物歧化酶活性表现为正相关关系,还原型谷胱甘肽与过氧化氢酶的相关系数为0.024,与超氧化物歧化酶的相关系数为0.183,超氧化物歧化酶与过氧化氢酶相关系数为0.203。灰色关联度、主成分分析和隶属函数综合评价得出3种藜科植物的重金属耐受性为四翅滨藜>盐爪爪>碱蓬。
英文摘要	In order to explore the physiological response and tolerance of three Familia Chenopodiaceae plants under heavymetal stress, three desert plants of Chenopodiaceae herbs, including Atriplex canescens (Pursh) Nutt, Kalidium foliatum (Pall) Moq and Suaeda glauca (Bunge) Bunge, were chosen as experimental plants and the pot experiment was conducted under different soil background, i.e. EG0, EG1 and EG2 in terms of cation exchange capacity, and heavy-metal ions content, to determine the physiological indexes of the three Chenopodiaceae plants, and then the tolerance of the Chenopodiaceae plants to heavy metal was analyzed by grey correlation analysis, principal component analysis and membership function. Under EG1 soil background the content of malondialdehyde and soluble protein in the plants increased, while the content of free proline decreased, and activity of catalase and superoxide dismutase declined significantly, peroxidase activity was increased to different degrees, but the peroxidase activity of Atriplex canescens notably decreased under EG2 background. Three principal components were selected from eight physiological indexes by principal component analysis, which were MDA factor, Pro factor and SOD factor, respectively. The grey correlation analysis showed that relation between the content of reduced glutathione and the activity of catalase and superoxide dismutase was positive; that the coefficient of correlation between reduced glutathione and catalase was 0.024, the correlation coefficient of reduced glutathione and superoxide dismutase was 0.183, and the correlation coefficient of catalase and superoxide dismutase was 0.203. According to the comprehensive evaluation of grey correlation analysis, principal component analysis and membership function, the heavy-metal tolerance of three Chenopodiaceae plants was shown in the descending order as Atriplex canescens>Kalidium foliatum>Suaeda glauca.
