Zn plays very important role in plant metabolism by influencing the activities of critical enzymes. Plant enzymes activated by Zn are involved in carbohydrate metabolism, maintenance of the integrity of cellular membranes, protein synthesis, regulation of auxin synthesis and pollen formation. The regulation and maintenance of the gene expression required for the tolerance of environmental stresses in plants are Zn dependent. RicoZinc has been developed for conditions where the deficiency of Zn is found in plants (high PH, water prolonged, negative effects caused by deficiency or excess of other elements, etc.) and while plant needs to get this element quickly.
