Abstract:
Taking the muskmelon variety ‘Nongda 103’ as the test material,the effects of magnesium on the nitrogen metabolism in the leaves of muskmelon seedlings was studied by the method of exogenous magnesium application,in order to provide a reference for the efficient cultivation of muskmelon.The result showed that，compared with CK,the nitrate nitrogen content of T1,T2 and T3 was significantly reduced,and the ammonium nitrogen content was significantly increased,while the T4 had no significant difference with CK.The activities of NR,GS,and GOGAT treated with T1,T2 and T3 were significantly higher than those of CK.The activity of NR treated with T4 was significantly higher than that of the control in the early stage,and showed a downward trend in the later stage.The activity of GS treated with T4 was significantly lower than that of CK,while the GOGAT activity was higher.Compared with CK and significantly lower than T2 and T3 treatment.Among the treatment concentrations,the 40 mg·L-1treatment had the best effect compared with other treatments.
