Abstract:
By the method of hydroponic culture，the effects of exogenous γ-aminobutyric acid (GABA) on active oxygen metabolism of roots and leave of ‘Xiyu No.1’ muskmelon under hypoxia stress were studied，in order to elucidate the mechanism of active oxygen metabolism of exogenous GABA in alleviating hypoxic stress injury of Melon.It showed that the activity of SOD,POD and CAT，and H2O2,MDA content and O?[TX-*4]2 productive rate of hypoxia stress treatment were all dramatically rised，compared to ventilation control.Exogenous 5 mmol?L-1 GABA could effectively alleviate the harm of hypoxia stress in roots and leaves of melon.Activities of SOD，POD and CAT of roots and leaves of melon plant dramatically rised,and O?[TX-*4]2 productive rate，the contents of H2O2 and MDA dramatically decreased.It suggested that exogenous GABA could increase the resistance of melon plant under hypoxia stress most likely by improvng the activity of antioxidant enzymes in plants and decreasing the accumulation of reactive oxygen species.
