中文摘要：

为考察离子液体在水和土壤不同环境介质中对高等植物的潜在毒性，分别采用水培和土培试验方法研究了不同浓度（0、100、200、300、400、500mg／kg）的离子液体1-甲基-3-乙基-咪唑缬氨酸盐（[C，mira][Val]）对小麦发芽率（7d）及生理特性（8-18d）的影响、实验结果表明：两种培养方式下，离子液体在浓度≥200mg／kg时对小麦种子萌发产生显著的抑制作用，且抑制效应具有典型的剂量依赖型特点。水培胁迫13d，离子液体浓度≥300mg／kg处理，及土培胁迫18d，离子液体浓度≥400mg／kg时，均造成小麦幼苗叶片SOD、POD酶活性降低，MDA含量显著升高：表明较高浓度的离子液体对高等植物具有一定的毒害作用，水培比土培加重了离子液体对小麦的毒害程度。

英文摘要：

This paper showed the potential toxic effect of ILs in different environmental media （ water and soil） on higher plants, by using water cuhure and soil cuhure respectively. The effee, t of ILs [ C2mim ] [ Val] on wheat germination rate （ 7 d） and physiologieal characteristics（8-18d） was studied in different concentrations （0, 100, 200, 300, 400, and 500 mg·kg^-1）. The results show that the wheat seedlings were inhibited obviously in the concentration of ,nore than 200 mg·kg^-1 of ILs. In addition, the inhibited effeel was dose-dependent under both euhivations. After treated 13 d with water at the concentration more than 300 mg·kg^-1 ILs and 18 d with soil at more than 400 mg·kg^-1 ILs, the activities of SOD and POD of the wheat seeding leaves both decreased while MDA increased obviously, which proves that the higher concentration of ILs has a certain toxic effect ou higher plants and the toxic effect of ILs on wheat under water culture was greater than that of soil culture.
