摘　　要：为探讨盐胁迫下燕麦幼苗耐盐性与生理生化指标之间的关系,采用沙培法对6个栽培燕麦品种进行盐胁迫处理(0、1、2、4、6、8g/kg NaCl),在播种7、14、21d时测定各处理下幼苗的生长指标和生理生化指标,并用单因素方差、相关性网络、隶属函数等方法进行数据分析。结果表明,耐盐指标间存在显著正相关关系,过氧化物酶活性、叶绿素含量与耐盐指标间存在显著正相关,丙二醛、可溶性糖、脯氨酸含量与耐盐指标间存在显著负相关;种子千粒重与耐盐指标、过氧化物酶及叶绿素含量之间存在显著负相关关系。In order to explore the relationship between salt tolerance and physiological,biochemical indexes of oat seedlings under salt stress,six oat varieties with salt stress(0,1,2,4,6,8g/kg NaCl)were treated by sand culture.The growth parameters and physiological,biochemical indicators of oat seedlings were measured on 7th,14th and 21th day.The data were analyzed by single factor variance,correlation network and membership function.The results indicated that there were significant positive correlation among salt tolerance indexes.There were significant positive correlation between peroxidase activity,chlorophyll content and salt tolerance index.There were significant negative correlation between malondialdehyde content,soluble sugar content,proline content and salt tolerance index.There were significant negative correlation between salt tolerance index,peroxidase,chlorophyll content and 1000-seed weight.
