| 摘 要： | 采用盆栽试验研究土壤中不同施芘水平对菠菜(Spinacia oleracea L.)生长、叶片叶绿素和抗氧化酶活性的影响.结果表明:50～200 mg·kg-1施芘水平下菠菜幼苗叶片的各项叶绿体色素含量、不同时期的根长与对照均无显著差异;施芘浓度大于50 mg·kg-1,菠菜苗期的株高、根和茎叶的鲜重显著降低;芘大于100 mg·kg-1时,菠菜收获期的根和茎叶干重显著受到抑制;芘胁迫导致菠菜幼苗叶片的丙二醛累积量提高,可溶性糖含量增加;同时叶片的APX、CAT、POD活性和非酶抗氧化剂AsA含量均随芘浓度增加而显著增加.

| Abstract: | An experiment was conducted in flowerpots to study the effect of the pyrene level in soil on the growth leaf,chlorophyll content and anti-oxidative enzyme activity of the spinach(Spinacia oleracea L.).No significant differences were found on the root length in different growth periods or the contents of chlorophyll a,chlorophyll b,chlorophyll a+b and carotenoid in the leaves,when 50-200 mg kg-1 pyrene was applied.However,when pyrene application was greater than 50 mg kg-1,significant reductions on plant hei... |
