A partial rootzone drying (PRD) irrigation technique (0.5 ML/ha) was compared with a standard irrigation treatment(1 ML/ha) at three different pruning levels of 30, 60 and 120 nodes per grapevine in Vitis vinifera L. cv Shiraz. The PRDirrigation technique... see more

Wine comprises a complex microbial ecology of opportunistic microorganisms, some of which could potentially inducespoilage and result in consequent economic losses under uncontrolled conditions. Yeasts of the genus Brettanomyces,or its teleomorph Dekkera,... see more
