Quelles cibles moléculaires pourraient expliquer l’effet du terroir sur la composition des baies en sucres et acides?

Context and purpose of the study. The vine is generally a very fertile plant when compared to other tree species.

The increase in temperature caused by climate change produces an earlier budbreak date that affects the vineyard, which generates a greater risk of damage by spring frosts.

Dans la Région de la Bairrada (Litoral-Centre du Portugal), on a étudié au 1999, l’influence des différents systèmes de conduite sur le cépage rouge “Baga”, le plus important de la Région.

Drought and heat stress will pose challenges for the future of viticulture and wine quality, as grapevine biological processes are pushed beyond their optimum conditions. Efforts are increasing to study and predict the effects of drought spells and heatwaves on grapevine physiology and resulting harvest quality. This calls for the development of adequate systems to induce and manipulate the required stress, especially in open field trials where conditions are more difficult to control. We present a semi-controlled system for studying drought and heat stress in grapevine in the field.

Ecological sustainability refers to developing viticulture in adequate environmental conditions.
