Series of Lectures – Effects of Drought and Heat Stress on Grapevine Physiology and Wine Quality

Ort: Laimburg Research Centre, Aula Magna

Abstract: Drought-induced water deficit stress on grapevine growth and subsequent effects on wine quality are of increasing concern in light of current climate trends. Many wine producing regions are located in areas with low water availability, and understanding the combined effects of heat and drought stress on wine grapes is critical to identifying solutions to promote healthy grapevine performance and berry quality. Through a series of experiments in the terraXcube climate chambers and in an experimental vineyard, we measured physiological response of vines to the aforementioned stressors. To examine the impact of abiotic stress on wine quality, microvinifications were carried out and underwent sensory analysis. Results indicate different methodologies for detecting plant stress, and that different grape varieties have more profound reactions to water deficit. Speaker: Amy Kadison (Laimburg Research Centre)
