摘　　要：初步探索小麦和玉米对石油污染土壤的耐受性,同时摸索这两种农作物在石油污染的胁迫下对石油污染土壤的潜在修复效果,以期为现场进行相关的植物修复提供理论依据。实验设置了0%、0.5%、1.5%、3%四组石油污染土壤处理,对小麦和玉米两种供试植物进行了温室盆栽观测试验。结果表明,受试植物的发芽率在石油的胁迫下均呈下降的趋势,并且当浓度达到3%时影响显著;石油对小麦和玉米的生长表现出抑制作用,其株高、叶片数、干物质量与对照相比有较明显的降低;小麦和玉米的叶绿素含量随着石油浓度的升高而降低;小麦叶片中丙二醛(MDA)含量及可溶性蛋白含量随着石油浓度的升高呈先增加后下降的趋势,而玉米种的MDA含量则是随着石油浓度的升高而升高,可溶性蛋白含量则是随着石油浓度的升高呈下降趋势。The experiment have been selected the Triticum aestivum Linnand Zea mays L. two different plants for 60 days imitate in the laboratory. According to measure the oil contaminated soil toleranceof two different plants and the oil pollution stress on petroleum contaminated soil restoration potential effect,which hope to provide a theory basis in future remediation cases. The experiment set up 0%,0.5%,1.5%,3% four groups of polluted soil respectively,and doing the experiment that culture the tested plants of wheat and corn in the greenhouse by pot. The results shows that the germination rate of tested plants in the petroleum coercion all shows downward trend,and have an extremely influence on the result when the density reach to 3%;The petroleum density to the wheat and corn have an inhibition actions,compare CK with the height,the number of leafs,the dry substance,which have an obvious descend trend. The content of chlorophyll decreased with the petroleum density increasing for wheat and corn. The content of MDA,soluble protein in the wheat leafs,which shows firstly increased and then decreased with the petroleum density increasing,but the content of MDA increasing with the petroleum density increasing,the content of soluble protein shows a decreased trend with the petroleum density increasing.
