Liquid dense foliar fertilizer – stimulator of special technology and composition that contains Potassium (K) and Nitrogen (N) for foliar spraying at the beginning of ripening, with the aim of improving the quality and especially the color of the fruits. Thanks to the MAC (Metabolically Active Compounds) technology of CYTOZYME and its special composition it achieves: 1) Improving the expression of the EPSP gene responsible for the production of the critical enzyme ESPS synthase, so that plants produce through the biochemical “pathway” greater amount of specific amino acids: tryptophan, tyrosine but mainly phenylalanine, which is a precursor of dyes (anthocyanins), phytoalexins and other phenolic substances. 2) Improving the efficiency of photosynthesis for the nutrition and ripening of the fruits but also the synthesis of pigments (anthocyanins and carotenoids). 3) Protection of plants and fruits from oxidative stress (stress) but also dealing with the effects of stress. 4) Increased concentration in the fruits of sugars, soluble solids and pigments. Synchronizes and promotes the ripening and the most intense and early coloring of the fruits of fruit crops (colored grape varieties, solanaceae, etc.), improving their quality.
