摘　　要：试验在盆栽人工控制水分的条件下,选用耐旱性不同的玉米杂交种沈单10、掖单13号和丹玉13号为试验材料,比较了不同水分胁迫强度对不同耐旱性玉米杂交种叶片光合作用的影响。结果表明,水分胁迫下玉米叶片光合速率随胁迫增强而下降,而在重度胁迫下光合速率显著下降。This experiment was carried out on the potted plants of maize. Three different maize varieties （Shendan 10, Yedanl3 and Danyul3） were chosen as experimental materials. This paper compared the effects of different water stress intensity on leaf photosynthesis of different drought-resistant maize hybrids. The results indicated that the photosynthetic rate of maize leaf under water stress went down with the increasing of water stress, and the photosynthetic rate decreased obviously under severe water stress.
