摘 要 ：试验结果表明，干旱胁迫下抗旱性不同的冬小麦品种的抗旱系数为：昌乐5号＞秦麦3号＞山农587＞济南13＞鲁麦5号＞烟农15。五个生育期的叶片渗透调节能力为抗旱性强的品种大于抗旱性弱的品种，抗旱系数和渗透调节能力是反映冬小麦抗旱特性的两个最好指标。拔节、孕穗和开花期抗旱性强的品种气孔阻力比抗旱性弱的品种大，灌浆和

Abstract:Six winter wheat cultivars were studied under drought stress and normal conditions to investigate their drought-resistant physiological characteristics. The results revealed that the order of the drought-resistant coefficients of the winter wheat cultivars studied was: Changle 5＞Qinmai3＞Shannong 5
