Participates in enzymes, assists in photosynthesis and distribution of carbohydrates. It is present in protein metabolism, reduction and nitrogen fixation.
It acts on the lignification of the cell wall, influencing the permeability of xylem vessels. Influence on flowering and fruiting and helps in disease resistance mechanism.
Deficiency – New deformed leaves; descending death of crooked branches, stems and branches; loss of lignification, leaving the branches and stem with a “fallen” aspect. Deformation of the new leaves with the death of the apical buds, budding of the lateral buds and formation of a bulge at the base of the lateral buds and without chlorosis in the leaves.
