摘要:
为探究植物在外源3-吲哚乙酸(IAA)作用下对重金属[铜(Cu)、铅(Pb)、锌(Zn)、镉(Cd)]污染土壤的修复效果,以江苏省某重金属复合污染区土壤为对象,通过盆栽种植紫花苜蓿和黑麦草2种先锋植物,研究3-吲哚乙酸对植物修复重金属污染土壤效果的影响。结果表明:IAA可促进植物在重金属污染的土壤中生长,紫花苜蓿和黑麦草株高、根长和生物量均比不添加IAA的处理显著高;相比于对照,各处理土壤重金属含量降低,其中IAA处理下黑麦草土壤Cu、Zn、Cd含量最低,IAA处理下紫花苜蓿土壤Pb含量最低;IAA作用下土壤重金属去除率和植物体内重金属含量提高,2种植物对4种重金属的生物富集系数(BCF)提高,但紫花苜蓿中Pb和Zn转运系数(TF)降低,黑麦草中Cu和Zn的TF不受IAA影响。综合分析,植物激素IAA可促进植物生长,对植物修复土壤重金属污染具有增效作用。
