| 20110281728 | METHOD FOR CONTROLLING COLORATION IN TABLE GRAPES BASED ON OLIGOGALACTURONIDES - The present invention claims a method making it possible to control the color of table grapes, color being a quality factor for the marketing thereof. The traditional color promotion pathways make use of products such as Ethrel and methyl jasmonate (MeJA), which liberate or induce ethylene to improve color, these being applied during veraison to augment the color of the berries determined by the quantity and composition of skin anthocyanins. One alternative to the use of these compounds are the oligogalacturonides (OGAs) having a degree of polymerisation in the range from DP 7-20 which have the capacity to induce anthocyanins by an alternative pathway. The synthesis and precise application of OGAs form a method permitting appropriate control of the coloration of this type of fruit, together with the quantification of total anthocyanins. | 11-17-2011 |
