摘要
The melon (Cucumis melo L.) cultivars Yuma and Gallicum were grafted onto three rootstocks of Cucurbita maxima: Shintoza, RS-841 and Kamel. The two melon varieties left ungrafted were used as control. The plants were grown under controlled conditions and fertilized constantly with both macro- and micronutrients. The total content of macronutrients (N, P, S, K, Na, Ca and Mg) and yield were determined in the aerial portion of both the control and grafted plants. A model was developed to determine the influence of the different rootstocks on the parameters analyzed, based on the differences between the control and grafted plants. Our results show that the use of the different rootstock genotypes causes little change in the leaf content of macronutrients, principally in N and Na. On the contrary, root genotype determined the yield. Finally, we found a strong relationship between the variations in foliar concentrations of N and Na and yield differences in grafted plants.
