摘要:
为了研究脱落酸(ABA)在小麦对涝渍胁迫响应过程中的生理作用,在涝渍胁迫条件下用0.05 μmol/L ABA喷施小麦叶片,检测逆境处理期间小麦叶片内超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)的活性,及丙二醛(MDA)含量和相对外渗电导率,并于收获后测产。生理指标测定结果表明,与对照相比,ABA处理可以显著提高涝渍条件下小麦叶片内SOD、POD及CAT活性,同时显著降低叶片内MDA含量及相对外渗电导率水平;测产结果表明,ABA处理可以显著提高涝渍条件下小麦的产量。可见,ABA可以提高小麦对涝渍胁迫的抗性,进而增加小麦在涝渍条件下的产量。
Abstract:
To investigate the effects of ABA on waterlogged wheat growth, 0.05 μmol/L ABA was sprayed on the wheat leaves, and the activities of super oxide dismutase (SOD), peroxidase (POD), catalase (CAT), the content of MDA, and relative electric conductivity as well as yield were measured. The results showed that ABA could significantly improve the yield and the activities of SOD, POD and CAT in leaves of wheat under waterlogging, meanwhile decrease the content of MDA and relative electric conductivity, indicating that ABA is capable of boosting the tolerance to waterlogging and improving the wheat yield.
