Plant phenolics have been for many years a theme of major scientific and applied interest. Grape berry phenolics contribute to organoleptic properties, color and protection against environmental challenges. Climate change has already caused significant warming in most grape-growing areas of the world, and the climatic conditions determine, to a large degree, the grape varieties that can be cult...

Anthocyanins (Anths) in grape (Vitis vinifera L.) berries harvested at véraison from Pinot Noir and Pinot Meunier cultivars were assessed nondestructively by measuring chlorophyll fluorescence (ChlF) excitation spectra. With increasing Anth content, less excitation light was transmitted to the deeper Chl layers, and thus the ChlF signal decreased proportionally. By applying Beer-Lambert's law, ...

Ripening progress in each class in relation to RS berries during the first 3-week period To assess the progress of ripening during early-véraison in GH, GS, and PS berries relative to that of RS berries, principle component analyses were performed using TSS, color index, and elasticity data of individual berries from each under-ripe berry class along with those of RS berry class during the firs...

In this paper energy bands and Berry curvature of graphene was studied. Desired Hamiltonian regarding the next-nearest neighbors obtained by tight binding model. By using the second quantization approach, the transformation matrix is calculated and the Hamiltonian of system is diagonalized. With this Hamiltonian, the band structure and wave function can be calculated. By using calculated wave f...

For production of high quality grape berries, the whole cluster should ripen at one time. The lack of uniform ripening within a cluster is termed "uneven ripening," and is characterized by the presence of green berries in an otherwise mature ripe cluster. Uneven ripening of 'Concord' is a major problem in the South, often prohibiting production. Northwest Arkansas is the southern boundary for c...

BACKGROUND: Small berry size is normally associated with quality wine production. However, the contribution of grapevine variety and environment to sensory has not been well established. In this study, genotypes from two intra-specific hybrid populations were categorized by according diameter weight: small ( 16 mm, >2 g). Chemical attributes wines produced in consecutive vintages (2017 2018) ea...
