Foliar applications to vines of methyl jasmonate and nanoparticles doped with methyl jasmonate: impact on grape and wine polysaccharide composition

Polysaccharides in wine play important roles the stabilization and sensory properties of wines. Elicitor application constitutes an interesting field research since it is indirectly involved accumulation grape cell walls molecules like callose, lignin, phenolic compounds glycoproteins. Currently, biomimetic calcium phosphate (ACP) nanoparticles are successfully used viticulture for controlled delivery bioactive molecules, such as elicitors. The aim this study was to compare effect two different elicitors on both Tempranillo polysaccharide composition. Methyl jasmonate (MeJ) doped with MeJ were applied canopy at veraison one week later vintages. In extracts, foliar treatments did not increase content monosaccharides or that main pectin families; therefore, reinforce grape. extractability solubility pectic families into depended type family climate
