Drought response of rootstocks is important for overall viticulture as a result of increase in water scarcity due to climate change and irrigation limitations in winegrowing region. Grapevines are generally well-adapted to arid and semi-arid climates, and they appear to primarily rely on drought avoidance mechanisms in water stress situations. In terms of the response of the grapevine to drought conditions, rootstock... Read more.
