| 摘 要： | 采用盆栽试验研究了重金属Cd(20 mg·kg-1)污染下,黑麦草-丛枝菌根对2个番茄品种生长、叶和根丙二醛(MDA)含量、抗氧化酶活性、Cd积累及化学形态的影响.结果表明,番茄果实干重和植株总干重、叶和根抗氧化酶活性及丙二醛含量、植株各部位Cd含量及积累量在不同品种和处理间的差异达到显著性水平.黑麦草和丛枝菌根单一或复合修复显著提高了2个番茄品种的果实、根、茎、叶及总干重,降低了叶和根的MDA含量及过氧化氢酶(CAT)、超过氧化物歧化酶(SOD)和过氧化物酶(POD)活性.黑麦草和丛枝菌根单一或复合修复降低了2个番茄品种果实中Cd提取总量和各形态Cd含量,降幅分别为19.4%~52.4%、31.0%~75.2%、19.7%~59.1%、3.1%~48.2%、20.0%~65.0%、40.7%~100.0%和15.2%~50.0%.Cd主要积累在番茄的叶和茎,果实和根积累较少.黑麦草和丛枝菌根单一或复合修复不同程度降低了番茄果实、叶、茎和根中的Cd含量;减少了茎Cd积累量和植株全Cd量."Cd+黑麦草+丛枝菌根"处理还减少了2个番茄品种果实的Cd积累量,降幅分别为42.9%和43.7%.供试2个番茄品种,以"洛贝琪"对Cd的耐性和抗性较强,果实Cd含量和积累量及植株Cd总积累量则以"洛贝琪"<"德福mm-8".
