摘  要：
通过水培试验,研究不同PAEs污染物及其浓度对7种作物的胁迫响应,以期为酞酸酯污染土壤的农作物栽培以及植物修复提供理论依据。结果表明,DMP、DEP、DOP的不同浓度处理对7种作物生物量的影响不同,7种作物的茎叶与根部对3种PAEs的响应也不同。冬瓜、豆角、番茄的茎叶对PAEs污染物的响应明显大于根部。DOP对黄瓜的根部无影响,DMP对香根草的根部无影响。胁迫响应综合评价结果显示,7种作物中对3种PAEs污染物胁迫响应为中度胁迫的有2种(豆角、番茄),重度胁迫的有5种(冬瓜、大豆、黄瓜、空心菜和香根草)。采用耐性指数法对不同作物的地上部生长、地下部生长耐性进行分类,属DMP普通型的作物有3种(番茄、冬瓜和豆角),属DEP普通型的作物有5种(番茄、大豆、空心菜、冬瓜和豆角),属DOP普通型的作物有2种(大豆、空心菜),香根草是DMP、DEP和DOP的耐性型作物。

摘  要：
The effects of 3 kinds of phthalate esters( PAEs) contaminated water on the growth and physiological characteristics of 7 crops grown in 3 kinds of phthalate esters( PAEs) contaminated water were studied through aquaculture experiment so as to provide the basis for crop cultivation and plant remediation.The result showed that effects of different treatments of 3 PAEs were different on biomass of the 7 crops,and the responses of the aboveground part( stem and leaf) and the underground part( root) of the 7 crops to 3 PAEs were different.The impact of 3 PAEs on the aboveground part of 3 crops( Benincasa hispida,Vigna unguiculata and Lycopersicon esculentum) was greater than that on the underground part.DOP had no impact on the underground part of Cucumis sativus,and DMP had no impact on the underground part of Vetiveria zizanioides.The evaluation the stress responses of 7 crops to 3 PAEs showed that it was moderate stress to 2 crops( V.unguiculata and L.esculentum) and severe stress to 5 crops( B. hispida,Glycine max,C. sativus,Ipomoea aquatic and V. zizanioides).7 crops were classified according to the tolerance index of aboveground and underground parts.3 crops( B. hispida,V.unguiculata and L.esculentum) had normal response to DMP.5 crops( L.esculentum,G.max,I.aquatic,B.hispida and V.unguiculata) had normal response to DEP.2 crops( G.max and I.aquatica) had normal response to DOP.V.zizanioides was a tolerant crop to 3 PAEs.
