Effect of vineyard management strategy on the nutritional status of irrigated « Tempranillo » vineyards grown in semi-arid areas

In 1979 an enlightened and farsighted business owner in an area and in an activity unknown to him and in 120 hectares of land cultivated with corn and wheat expressed to one of us that he wanted to start a business in the wine sector. The first innovative “Vigna Dogarina Scientific Applicative Project” has become famous and harmoniously inserted in and with the “Territoir” of eastern Veneto in northeastern Italy. The revolutionary project allowed one of us: 1. to put into practice results of research related to the applied philosophy, vision, methodology of the “Great MetaEthic Chain 4.1C®” algorithm of the “Conegliano Campus 5.1C®” that considers all material, immaterial, spiritual, technical, economic, environmental, social, existential, relational, ethical, MetaEthical factors with basic indexing in a harmonious chain “ 4.1C®” and application “5.1C®”, 2. to implement:

Context and purpose of the study. Modern conventional agriculture, including viticulture, relies greatly on the use of chemical inputs, especially synthetic pesticides.

In-season vineyard pest management relies on proper timing, selection, and application of products. Most of the research on pest management tends to focus on the influence of regional conditions on these aspects, with an emphasis on product timing and efficacy evaluation. One aspect that is not fully vetted in various vineyard regions is application (sprayer) technology. The purpose of this study was to determine the influence of regional conditions on sprayer performance in commercial wine grape vineyards in eastern Washington.

Phenolic compounds are important quality indicators in red wine. A large number of polyphenols play an important role in wine development, contributing to the colour and the sensory perception of the wines. Anthocyanins are the pigments responsible for the colour in young red wines while tannins are the principal contributors to the bitterness and the astringency of the wines. Wine polyphenols are considered more complex molecules than grape phenolics, due to the enormous number of chemical reactions which take place during the entire winemaking process and storage, forming more stable compounds.

Grapevine (Vitis spp.) is a globally significant fruit crop, and enhancing its agronomic and oenological traits is crucial to meet changing agricultural conditions and consumer demands. Conventional breeding has played a key role in domesticating grapevine varieties, but it is a time-consuming process to develop new cultivars with desirable traits for cultivation.
New plant breeding techniques (NpBTs) offer a potential revolution in grapevine cultivation, and genome editing has shown promise for targeted mutagenesis. The success of these biotechnological approaches relies on efficient in vitro regeneration protocols, particularly through somatic embryogenesis (SE).
