Minority grapevine varieties as climate change adaptation strategy: Exploring heat tolerance plasticity

نویسندگان

چکیده

Climate change is increasing average temperatures and intensity frequency of extreme events such as heat waves. Productivity declines plant damage due to those changes are already described for several majority varieties, especially in the Mediterranean basin. Less explored minority varieties can arise alternatives high tolerance, or having acclimation potential heat. We evaluated tolerance after three summer thermic environments four Spanish varieties: two (‘Tempranillo’, ‘Airén’) (‘Jarrosuelto’, ‘Morate’). Summer differed temperature, length warm period. Varieties its plasticity environments. Within ‘Tempranillo’ showed low moderate highlighting susceptibility climate change. ‘Airén’ had slightly higher than certain adaptation capacity minority, ‘Jarrosuelto’ but plasticity. ‘Morate’ was variety with highest plasticity, indicating strong adaptive potential. Majority displayed global warming negative effects. However, offer solutions either by acclimation.

The challenge of adapting grapevine varieties to climate change

Climate change is expected to advance grapevine phenological stages. After the calibration and the validation of a degree-days model, we were able to accurately simulate dates of budbreak, flowering and véraison for Riesling and Gewurztraminer, 2 winegrape varieties grown in Alsace, France. Projected daily temperatures were calculated for the local meteorological station with the ARPEGE-Climat ...

Climate Change Adaptation: Weighing Strategies for Heat-Related Health Challenges

Many public health impacts have been predicted for climate change, but there has been relatively little exploration of ways to minimize the risks and develop long-term adaptation strategies. A new overview outlines the critical elements needed to address one such impact: heat-related illnesses and deaths, which are expected to increase with more frequent and more intense heat waves [EHP 121(4):...
