摘　　要：通过干旱胁迫试验和蒸腾量的测定对花生品种的节水耐旱机理进行分析,结果显示,花生品种节水耐旱的机制表现为:①花生的根系发达,主根长;②蒸腾量少;③耐干旱胁迫型的花生品种抵御干旱的能力较强。Characters of drought tolerance in groundnut genotypes were investigated by artificial drought stress treatment. The results indicated that the mechanisms of tolerance to drought in groundnut including their longer and more roots, lower transpiration rate and physiological as well as biological characters.
