Abstract:: Most quality wines are produced in areas where annual precipitation is below 700 to 800 mm (Jackson & Schuster, 1994), and evidence suggests that high rainfall or excessive irrigation lowers quality. Excessive irrigation is reported to slow ripening, increase yields partially berry enlargement, elevate juice pH and acid content, and...

Abstract:: This study integrates various vineyard practices that may improve nitrogen availability to the vine, particularly during ripening. Different strategies aimed at improving fermentation behavior and wine quality are being evaluated. This study aims to optimize fruit quality and maximize the juice nitrogen fraction that can be used by yeast during...

Abstract:: Agrobacterium vitis is a bacterium that causes crown gall in grapevines. Plant injury from freezing temperatures or mechanical damage during cultivation often provide wounds required for infection to occur. Crown gall may kill grapevines and a new shoot is often brought up from the root to replace dead vines. Discovery...
