Abstract: In Greenhouse experiment, we studied the effects of wheat (Triticum aestivum L.)intercropping on the nitrogen metabolism during the senescence of cucumber (Cucumis sativusL.) leaves. The results showed that compared with cucumber monoculture, intercropping withwheat increased the content of soluble protein, nitrate nitrogen, free amino acid and proline andenhanced the activity of nitrate reductase (NR), glutamine synthase (GS), glutamatedehydrogenase (GDH) and glutamate synthase (GOGAT) of cucumber leaves. The qRT-PCRanalysis revealed that compared with cucumber monoculture, the expression of N1, N2 and N3,which belong to NRT (Nitrate Transporter Protein) family and A1, which belong to AMT(Ammonium Transporter Protein) family and GS1 (cytosolic glutamine synthase gene) wereup-regulated in intercropped cucumber. In short, the cultivation mode of intercropping withwheat increased the content of nitrogen compounds and enzyme activity and promoted theexpression of genes related to nitrogen metabolism in cucumber leaves, which delayed thesenescence of cucumber leaves.
