Grape ripening timing as a base for viticultural zoning: an agro-ecological approach

Abstract

Due to the central role of the ripening timing in the evaluation of the varietal response to the environmental resources, a method to manage maturation curves has been developed. The method produces an index of veraison precocity and overcomes several methodological problems, like the visual evaluation of the veraison point and the multi-annual and multi-varieties data processing. It is based on a statistical and mathematical processing of the sugar ripening curves. The index resulted satisfactory correlated with flowering time and sugar level at vintage, it allowed to study the effects of environmental resources on the timing of ripening and to classify the vineyards, and the relative land units, into homogeneous groups for what concerns precocity of veraison. For these reasons it demonstrated to be useful for zoning projects.

Portable NIR spectroscopy for nutrient profiling in rootstock and scion material: enhancing decision-making in the grafting industry

The success of grafting in viticulture is deeply influenced by the nutrient composition of both rootstock and scion materials. Key components such as nitrogen and carbohydrates play a crucial role in graft compatibility, establishment, and overall plant vigor [1].

Variability of Constitutive Stilbenoid Levels and Profiles in Grape Canes (Vitis spp.) depending on Genetic and Environmental Factors

Grape cane is a viticultural by-product that is currently underused or not used at all. Therefore, it bears a high potential for valorization due to the presence of anti-microbially active stilbenoids, being biologically relevant for plant defense. These compounds are highly interesting for applications in the agricultural sector as well as for the food and feed industry.
