图2 干旱及外源ALA处理对不同抗旱性小麦叶绿素、MDA含量以及抗氧化酶活性的影响 数据为3次重复的平均值±标准差, 图中不同字母表示品种内处理间有显著差异(P < 0.05)。CK: 正常供水; Drought: 干旱处理; D+A: 干旱处理之前用外源ALA预处理。

Fig. 2 Effects of drought stress and exogenous ALA on the chlorophyll and MDA contents, and the activities of antioxidant enzymes for different drought-resistant wheat cultivars Data are means ± standard deviations of three replicates. Different letters indicate significant difference among treatments within each cultivar at P < 0.05. CK: normal water supply; Drought: water deficit treatment; D+A: exogenous ALA pretreatment prior to water deficit treatment.
