水分胁迫对玉米萌芽期保护酶系活力影响及其与抗旱性的关系

Effect of Water Stress on Protective Enzyme Activities and Relation with Drought Resistance in Seedling Emergence Stage of Maize

玉米种子在萌发出苗阶段,水分胁迫诱导了POD和CAT活性的升高。但POD与CAT的活性水平与品种萌芽期的抗旱性不存在明显的相关性,不宜作为萌芽期抗旱性鉴定的生理生化指标。

Water stress induced the activities of POD and CAT increasing in seedling emergence stage of maize. But there were no obvious relation between activities of POD, CAT and drought resistance. The results suggested that activities of POD and CAT couldn't be used as an appraisal indexes of drought resistance in seedling emergence stage of maize.
