摘　　要：本文测试了S-诱抗素叶面喷施处理后玉米植株在高温干旱协迫下水分消耗等项目,结果表明:S-诱抗素处理可以缩小气孔导度,减少叶片蒸腾速率,提高了玉米植株的保水能力,减少了水分消耗。In this trial,the effect of foliar spraying S-ABA on the water consumption of corn plant under high temperature and drought stress was studied.The results showed that the leaf stomata conductance fall,and the leaf transpiration rate decreased,and the corn plant water consumption decreased by spraying S-ABA under the high temperature and drought stress.

关 键 词：S-诱抗素 玉米 气孔导度 蒸腾速率 水分消耗
