摘要
以10个番茄品种为试材,研究了不同根际低氧时间对番茄体内超氧化物歧化酶(SOD)活性的影响,以解决水培番茄栽培中根际低氧问题,促进水培番茄技术大面积推广。结果表明:根际低氧胁迫在低氧初期可促进酶活性的提高,随着根际低氧胁迫时间增加,酶活性降低;而且不同番茄品种在根际低氧胁迫环境中酶活性的降低程度不同,品种之间存在差异。在根际低氧胁迫条件下,SOD活性较强的番茄品种为‘紫玫瑰’,SOD活性较弱品种为‘丹红F1’。
10tomato varieties were used as materials,different rhizosphere hypoxia stress on SOD of hydroponics tomato were carried out,in order to promote hydroponic tomato technology in large scale,to solve hydroponic tomato cultivation in the root zone hypoxia problem.The results showed that,the rhizosphere in the early hypoxic hypoxia stress could promote the activity,activity increased in the rhizosphere hypoxia with time decreased;different tomato varieties and hypoxic environment in the rhizosphere caused different degree of reduced activity,and there were differences among varieties.Under hypoxic conditions rhizosphere,tomato variety‘Zimeigui＇had strong SOD activity,variety‘Danhong F1＇had weaker SOD activity.
