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.
