摘要:
为明确DA-6、DCPTA浸种处理对绿豆耐旱性的增强效应,研究干旱胁迫下DA-6、DCPTA浸种处理对绿豆种子萌发及芽期的影响,以2种绿豆种子为试验材料,在干旱胁迫(15%PEG-6000)下,使用不同浓度DA-6(5、10、15、20 mg/L)和DCPTA(0.010、0.025、0.075、0.250 mg/L)对绿豆种子进行浸种处理,测定发芽势、发芽指数、抗旱指数、根长、上胚轴长、下胚轴长等形态指标,并测定绿豆芽期的超氧化物歧化酶(SOD)活性、过氧化物酶(POD)活性、过氧化氢酶(CAT)活性、丙二醛(MDA)含量等生理指标。在干旱胁迫下,与对照组相比,DA-6、DCPTA浸种处理显著提高了绿豆种子的发芽势、发芽指数、抗旱指数、根长、上胚轴长、下胚轴长,芽期的SOD、POD、CAT活性显著上升,MDA含量显著降低,其中 15 mg/L DA-6、0.025 mg/L DCPTA浸种处理对干旱胁迫下绿豆种子萌发和芽期生长影响的缓解效果最为显著。结果表明,15 mg/L DA-6、0.025 mg/L DCPTA浸种处理能够显著提高绿豆种子的形态指标与抗氧化酶活性并降低MDA含量,增强绿豆的抗旱能力。
