δ¹³C : A still underused indicator in precision viticulture  

Introduction and objective: the practice of physical exercises in an exhaustive way is related to damage. Muay thai (mt) is a high-intensity sport that demands agility, strength and power, which can lead to fatigue and muscle damage. Grape juice is rich in carbohydrates and antioxidants, which can delay the onset of fatigue and muscle damage. The objective of the study was to evaluate the impact of white grape juice consumption, during 14 days, on muscle damage parameters in tm athletes.

Plants have been shown to redistribute water between root sections and soil layers along a gradient of decreasing water availability. One benefit of this hydraulic redistribution is that water can be transported from roots in wet soil to others in dry soil, delaying the onset of water stress and increasing root longevity in dry environments. Grapevines are thought to redistribute water laterally across the trunk from wet to dry portions of the root system. However, it is unknown whether the phloem contributes to such water redistribution.

In California vineyards, irrigation is considered as one of the most important decisions growers will make. Recent research has revealed that decisions of when to begin irrigation and how much water to apply have considerable consequences for final grape quality and hence wine quality. However, it is unclear whether and to what extent the average winegrape grower uses objective data to begin irrigating or to determine the amount of water to apply.

Global change in climate affect regional climates and hold implications for viticulture worldwide. Despite numerous studies on the impact of projected global warming on different regions

Mannoproteins (MPs) with different structure of their polysaccharide part (branching, substitutions, …) were used to better understand the impact of characteristics of the usual structure of MPs when interacting with Grape Seed Tannins (ST).
