S-诱抗素对玉米植株水分消耗的影响

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 com 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 com plant water consumption decreased by spraying S-ABA under the high temperature and drought stress.
