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0.05μmol/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。
為瞭研究脫落痠(ABA)在小麥對澇漬脅迫響應過程中的生理作用,在澇漬脅迫條件下用0.05μmol/L ABA噴施小麥葉片,檢測逆境處理期間小麥葉片內超氧化物歧化酶( SOD)、過氧化物酶( POD)、過氧化氫酶( CAT)的活性,及丙二醛( MDA)含量和相對外滲電導率,併于收穫後測產。生理指標測定結果錶明,與對照相比,ABA處理可以顯著提高澇漬條件下小麥葉片內SOD、POD及CAT活性,同時顯著降低葉片內MDA含量及相對外滲電導率水平；測產結果錶明,ABA處理可以顯著提高澇漬條件下小麥的產量。可見,ABA可以提高小麥對澇漬脅迫的抗性,進而增加小麥在澇漬條件下的產量。

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.
