Effect of Irrigation, Glycine Betaine and Kaolin Particle Film on the Performance of Vitis Vinifera L. ‘Shiraz’

Abstract

Environmental stresses, such as heat and water stress, are a current and emerging challenge to wine grape production in Australia. In Southern Australia, where wine grape production is predominately located, Global Circulation Models (GCMs) predict further increases in temperatures, increased frequency and severity of heatwaves and reduced rainfall. Wine grapes are particularly susceptible to heat and water stress due to the lengthy grapevine establishment times and the perennial nature of this crop. Therefore, there is a strong demand for management strategies to protect established vineyards from environmental stresses, such as heat and water stress. Glycine betaine (GB) and kaolin partic..
