AB  - This study investigated the effects of grafting on the carbohydrate status and 
      the enzymes of carbohydrate metabolism in self-grafted and grafted cucumber 
      seedlings using the salt-tolerant pumpkin rootstock 'Qingzhen 1' (Cucurbita 
      maxima x Cucurbita moschata) under 80 mM Ca(NO3)2 stress for 6 d. The growth of 
      self-grafted seedlings was significantly inhibited after the treatment of 
      Ca(NO3)2 stress, whereas the inhibition of growth was alleviated in pumpkin 
      rootstock-grafted seedlings. Ca(NO3)2 stress increased the contents of the total 
      soluble sugar, sucrose and fructose, but decreased the starch content in 
      rootstock-grafted leaves. However, compared with self-grafted plants, 
      rootstock-grafted seedlings were observed with a higher content of sucrose and 
      total soluble sugar (TSS) under salt stress. Rootstock-grafted seedlings 
      exhibited higher activities of acid invertase (AI), neutral invertase (NI) and 
      phosphate sucrose synthase (SPS) of sucrose metabolism in leaves than that of 
      self-grafted seedlings under salinity. Moreover, the activities of fructokinase 
      (FK), hexokinase (HK), phosphofructokinase (PFK) and pyruvate kinase (PK) of 
      glycolysis were maintained at a higher level in leaves of rootstock-grafted 
      seedlings after Ca(NO3)2 stress. Additionally, rootstock-grafting decrease the 
      high percentage enhancement of key enzymes gene expression in glycolysis in the 
      scion leaves of cucumber seedlings induced by salt stress. These results suggest 
      that the rootstock-grafting improved salt tolerance, which might play a role in 
      elevated sucrose metabolism and a glycolytic pathway regulated by the pumpkin 
      rootstock.
