Table 4
The relationship between the concentrations of major and trace elements studied in soils and leaves from grapevine cultivars of Alcubillas are represented in Figure 2. It can be seen that the higher the soil contents in Sr, Pb and Cr, the higher the contents of the same elements incorporated in the leaves. AmorĂ³s et al. (2012b) found a positive correlation between the amount of Sr in the soil and that in the leaf and grape. A similar trend was observed for Cu, Zn and, to a lesser extent, Ba, but less markedly than for the previous elements. Finally, the content of V in the leaf decreases as the content in the soil increases.
All of these data provide relevant information that could help to ascertain the nutritional status of the plant. Nevertheless, significant correlarions were not found in this survey; the uptake of elements in grapevine can be influenced by soil, climate, geographic origin, and rootstock type.
