Abstract:

摘要以耐旱性不同的2个品种番茄(‘毛粉802’和‘皇冠’)为试材,采用营养液栽培,研究了聚乙二醇(peg)模拟的干旱胁迫下喷施外源亚精胺(spd)对番茄幼苗活性氧(ros)水平和抗氧化系统的影响.结果表明,喷施0.1mmoll-1spd降低了7.5%peg胁迫下2个品种番茄幼苗叶中超氧阴离子(o2-?)产生速率、过氧化氢(h2o2)、丙二醛(mda)含量的上升,增加了超氧化物歧化酶(sod)、过氧化物酶(pod)、过氧化氢酶(cat)以及asa-gsh循环中抗坏血酸过氧化物酶(apx)、谷胱甘肽还原酶(gr)的活性,提高了抗氧化物质抗坏血酸(asa)、还原型谷胱甘肽(gsh)的含量,对单脱氢抗坏血酸还原酶(mdhar)、脱氢抗坏血酸还原酶(dhar)活性没有影响.耐旱性较强的‘毛粉802’幼苗叶中抗氧化酶活性和抗氧化剂升高幅度明显大于耐旱性较弱的‘皇冠’,ros积累速度和膜脂过氧化程度相对较低,喷施spd处理对‘皇冠’效果更为明显.这表明外源spd通过减少干旱胁迫下番茄幼苗体内ros的产生,提高植株体内抗氧化系统中抗氧化酶活性、抗氧化剂含量和降低膜脂过氧化水平,起到缓解干旱胁迫对番茄幼苗伤害的作用,增强幼苗对干旱逆境的适应性.图4参32
