Interactive effects of high temperature and water deficit on Malbec grapevines

Background and Aims Studies of the interactive effects of drought and high temperature on the physiological responses of grapevines (Vitis spp.) are scarce. We tested whether well-watered, potted vines were able to avoid heat waves through evaporative cooling in comparison to those suffering from water deficit. Methods and Results A greenhouse experiment was conducted with own-rooted Malbec grapevines under two water regimes, well-watered (100%...
