Hyperspectral imaging and machine learning for monitoring grapevine physiology

This work aims at identifying the most appropriate marketing strategies to inform consumers of the global market about the added value of the wines of Friuli Venezia Giulia.

Prizren’s vineyard territory-y assigned for ecological production of grapes and wine includes 1. 200 hectares of vineyard located in five separate localities which belongs to the P KB “Kosovo vina”, Mala Krusa in Prizren. Division of vineyard territory in zones was carried out in 1974. Pertaining to the vineyards, the climate and soil conditions have been studied and determined as well as topographie establishing of vineyard boundaries.

The ‘Erbaluce‘, a grapevine cultivar from which in the Canavese (Piedmont, Italy) different types of white DOC wines are obtained, is traditionally trained on a support structure commonly known as “pergola” having three to five long “cords” which consist of three cordons and canes interlaced together.

Root architecture (RSA), the spatial-temporal arrangement of a root system in soil, is essential for edaphic resources acquisition by the plant, and thus contributes largely to its productivity and adaptation to environmental stresses, particularly soil water deficit. In grafted grapevine, while the degree of drought tolerance induced by the rootstock has been well documented in the vineyard, information about the underlying physiological processes, particularly at the root level, is scarce, due to the inherent difficulties in observing large root systems in situ. The aims of this study were (i) to determine the phenotypic differences in traits related to root distribution and morphology along the substrate profile in different Vitis rootstocks during early growth, (ii) to assess the plasticity of these traits to soil water deficit and (iii) to quantify their relationships with plant water uptake.

Commercial red wines use the malolactic fermentation process to ensure stability from a microbiological point of view. In this second fermentation, malic acid is converted into L-lactic acid under controlled steps.
