摘要:
以竹节草为材料,研究莠去津、硝磺草酮及两者混合施用对竹节草色素浓度、脂质过氧化反应和抗氧化酶活性的影响。结果表明,随着硝磺草酮以及莠去津与硝磺草酮混合液浓度的增加及处理时间的增加,竹节草的损伤度表现出逐渐增强的趋势;硝磺草酮140 g a.i./hm2、莠去津280 g a.i./hm2及两者混合处理后,竹节草叶片的叶绿素a、叶绿素b和类胡萝卜素含量下降;超氧化物岐化酶(SOD)、过氧化物酶(POD)和过氧化氢酶(CAT)活性增强,而丙二醛(MDA)含量和超氧阴离子产生速率则出现先上升后平缓的趋势;莠去津和硝磺草酮混合施用比单独施用莠去津或硝磺草酮对竹节草具有更大的伤害(P<0.05)。
