摘要
[目的]研究在盐胁迫下小麦苗期叶片的抗氧化保护酶活性变化,为耐盐小麦品种选育提供依据.[方法]采用盆栽试验,设置0(对照)、100、150、200、250和300 mmol/L 6个盐浓度处理,测定盐胁迫下石4185和豫麦47的苗期抗氧化保护酶活性等指标.[结果]石4185的过氧化氢酶(CAT)、过氧化物酶(POD)和超氧化物歧化酶(SOD)活性均比豫麦47高.[结论]石4185比豫麦47具有更强的抗氧化保护系统,具有更强的耐受盐胁迫的能力.
Abstract
[Objective] The aim was to research the changes on the ability of antioxidant protection system of wheat seedling under salt stress to lay the foundation for the breeding of salt-tolerant wheat varieties.[Method]By the pot test,we set six salt concentrations such as 0(CK),100, 150,200,250 and 300 mmolL/to test the antioxidant enzymes of Shi 4185 and Yumai 47 under the salt stress in seedling stage.[Result]The ac-tivity of CAT,POD and SOD of Shi 4185 were higher than that of Yumai 47.[Condlusion]It illustrated that Shi 4185 has stronger antioxidant pro-tection system than Yumai47 and stranger ability to tolerate salt stress .
