摘　　要：利用PEG高渗溶液，研究在渗透胁迫条件下花生种子萌发特性及其作为芽期抗旱指标的可靠性。结果表明：不同品种在不同性状上表现受抑程度不同，用单一性状确定品种的耐旱性是不准确的。而以萌发率、胚根长和胚根于重3个性状的对照比为指标，参试品种进行系统聚类分析，筛选耐旱品种和田间鉴定结果基本相符。可以认为在高渗溶液中花生种子萌发特性的综合表现作为筛选耐旱品种的指标是有效的。The seed germination characteristics were checked in different levels by osmotic stress with the different of characters and peanut varities. Any single germination character as a drought resistant index was one-sideness, a better way to asess the drought resistance of peanut in ernbrynie stage was using the relative germination percentage, length and weight of radicles as indexes of system cluster anylsis and then classfying the varieties into different drought-resistant types according to the system cluster diagram.
