中文摘要	为提高燕麦种子在干旱条件下的萌发率,本研究利用五种外源物质对PEG- 6000胁迫下三个燕麦品种进行处理,对不同处理下燕麦品种的发芽指标、可溶性蛋白、过氧化物酶(POD)、丙二醛、相对电导率等指标进行分析,利用相关系数法及隶属函数法进行综合评价,筛选出缓解受干旱胁迫的燕麦种子萌发的最佳外源物质及浓度。结果表明:最佳缓解物质为S-诱抗素,可以显著提高三种燕麦种子发芽指标及可溶性蛋白等生理指标,降低丙二醛、相对电导率含量,增强对干旱胁迫的防御性。此研究将为干旱区燕麦生产提供理论依据。
英文摘要	In order to improve the germination rate of oat seeds under drought conditions,three oat varieties under PEG- 6000 stress were treated with five exogenous substances,and the germination index,soluble protein and peroxidation of oat varieties under different treatments were studied.The enzymes (POD),malondialdehyde,relative conductivity and other indicators were analyzed,and the correlation coefficient method and membership function method were used to comprehensively evaluate the optimal exogenous substances and concentrations for alleviating the germination of oat seeds under drought stress.The results showed that the best alleviating substance was S-excitation,which could significantly improve the germination index and soluble protein of three oat seeds,reduce the content of malondialdehyde and relative conductivity,and enhance the defensiveness against drought stress.This study will provide a theoretical basis for oat production in arid regions.
