Watermelon (Citrullus lanatus [Trumb.] Mansfeld cv. Early Star), was used as scion grafted onto three cultivars of pumpkin (Cucurbita pepo L. cvs. Brava, Shintoza and Kamel) used as rootstocks and ungrafted Early Star plants were used as control. The rootstocks showed a high capacity for N uptake and transport to the scion where N reduction and assimilation improved growth of the scion in grafted plants with respect to the control.

Keywords: amino acids; proteins; nitrate reductase; nitrite reductase
Subjects: amino acids, grafted watermelon; Citrullus lanatus; Cucurbita pepo; nitrate reductase, grafted watermelon; nitrite reductase, grafted watermelon; nitrogen supply, grafted watermelon plants; protein content, grafted watermelon; pumpkin, grafting watermelon; watermelon, grafted plants, N metabolism
