【目的】准确掌握冬小麦旱后复水下的形态变化规律及水分利用情况。【方法】采用盆栽试验方法,选取2个不同抗旱性的冬小麦品种(陇鉴108与西平1号)为试验材料,以全生育期充分供水处理为对照(CK),于返青—拔节期、返青—孕穗期、返青—灌浆初期进行不同程度干旱胁迫后,分别在拔节期、孕穗期及灌浆初期进行复水,分析研究了各时期干旱胁迫后复水处理对不同小麦生长发育及水分利用效率的影响。【结果】返青期中度干旱复水处理下,不同抗旱性冬小麦的生长发育、产量要素及水分利用效率均超过相应CK水平,尤其表现在水分利用效率上,陇鉴108为1.224 kg/m3,西平1号为1.033 kg/m3,发生超补偿效应;拔节期中度干旱处理下只有抗旱性强的品种陇鉴108的穗粒数、千粒质量及产量比CK略有增加,但增加不显著;其他干旱...
