This project investigated the physiological responses of grapevine to deficit irrigation strategies including partial rootzone drying (PRD) and regulated deficit irrigation (RDI). The principle objectives of the project were to (1) establish if the response to partial rootzone drying (PRD) is as a consequence of irrigation amount or a unique vine physiological response to PRD; (2) to investigate the effect of limiting environmental conditions on vine responses to PRD and deficit irrigation; (3) to investigate the effect of PRD and deficit irrigation on berry metabolism and maturation; and (4) effect of PRD and deficit irrigation on vine water-use. The experiment used field-grown Shiraz grapevines in a commercial vineyard in the Strathbogie Ranges in north-eastern Victoria. The experiment ran from season 2001/2002 through to 2003/2004 in a medium vigour, warm climate vineyard, with soils of low water holding capacity. (For complete abstract open document)
