Stomatal behaviour of three minority grapevine varieties grown in the La Mancha region (Spain)

Previous results have shown the impact of the pH on the stability of white wine proteins. In a context of global warming that implies increases in ethanol content and pH

Endogenic diseases often arise from pathogens that exist within the plant tissue, including fungi, bacteria, and viruses, which can remain latent and then emerge under stress conditions or favorable environmental conditions, causing symptoms that weaken vines or can lead to plant death.

In addition to studies on the edaphic and landscape characteristics of the environment (Dolédec, 1995), the characterization of the physiology of the vine and of parasitism during its vegetative cycle represents an essential component of knowledge and management of the terroirs.

The study of technologic and phenolic maturation is very efficient to determinate quality potential of red grapes cultivars and clones under different maturity levels or geographic origins

According to the vintage, it may be difficult for vine growers to make a decision regarding the type of wine in relation with the soils.
