摘要:
以大叶醉鱼草(Buddleja davidii Franch.)种子和幼苗为研究对象,分别采用加有蒸馏水(CK)与5%、10%、15%、20%、25%等5个不同质量分数(下同)聚乙二醇6000(PEG-6000)的发芽床蒸馏水(CK)与10%、20%、30%等3个质量分数PEG-6000模拟不同程度的干旱胁迫,研究干旱胁迫条件对大叶醉鱼草种子萌发及幼苗生理生化特性的影响。结果表明:(1)在一定范围内,随着干旱胁迫强度的增加,大叶醉鱼草种子的发芽启动时间推迟,发芽持续时间延长,发芽率、发芽势、发芽指数降低,但种子发芽率在 5%~10% PEG胁迫下与对照间无显著差异,而在15%PEG胁迫下均显著低于对照,在20%及以上质量分数PEG胁迫下种子不能萌发。(2)大叶醉鱼草幼苗叶片的游离脯氨酸、丙二醛含量随PEG胁迫强度的增加和时间的延长而增加,各指标均在30%PEG胁迫处理9 d时最高,分别为对照的2.88、5.66倍。(3)随着PEG胁迫时间的延长,大叶醉鱼草幼苗叶片过氧化氢酶(CAT)、超氧化物歧化酶(SOD)活性先上升后下降,在30%PEG胁迫处理6 d时活性最强;过氧化物酶(POD)活性随着胁迫时间的延长呈现出先下降又上升的变化趋势,并在30%PEG胁迫处理3 d时活性最强。由结果可得,大叶醉鱼草种子在轻度干旱胁迫下可正常萌发,而且幼苗能通过调节体内渗透调节物质含量和抗氧化酶活性主动适应干旱环境,对干旱环境表现出较好的适应能力。
