Vine plant material: situation and prospect

Abstract

vine plant material is one of the major factors of terroir. The vine numbers over 1,000 species, of which the main cultivated species, Vitis vinifera, includes some 6,000 varieties. For the last forty years, selection has been carried out on these, mainly through clonal selection. However, today, only 300 varieties present one or more clones. A dozen varieties are considered as international. The extreme requirements of selection, in terms of diseases, provoke the elimination of the majority of selected plants. This approach to selection is not thorough because it focuses mainly on elimination of virosis and phytoplasma diseases.
The only way to preserve vine biodiversity is mass selection. If the international vineyard community fails to preserve the genetic resources of viticulture, vine selection in the future will be limited to crossbreeding or genome modification. Yet even these approaches require considerable biodiversity. It is necessary to create a world inventory of old (more than forty years) vine plots, and to ban pulling up before sampling for selection. Mass selection has to be financed by all the actors of the wine and vine business in order to preserve access for all vine growers. International technical and financial assistance has to be rapidly implemented.

Hyperspectral imaging for precision viticulture

Precision viticulture aims to optimize vineyard management by monitoring and responding to variability within vine plots. this work presents a comprehensive study on the application of hyperspectral imaging (hsi) technology for monitoring purposes in precision viticulture. authors explore the deployment of hsi sensors on various platforms including laboratory settings, terrestrial vehicles, and unmanned aerial vehicles, facilitating the collection of high-resolution data across extensive vineyard areas.

Inert gases persistence in wine storage tank blanketing

It is common to find tanks in the winery with wine below their capacity due to wine transfers between tanks of different capacities or the interruption of operations for periods of a few days. This situation implies the existence of an ullage space in the tank with prolonged contact with the wine causing its absorption/oxidation. Oxygen uptake from the air headspace over the wine due to differences in the partial pressure of O2 can be rapid, up to 1.5 mL of O2 per liter of wine in one hour and 100 cm2 of surface area1 and up to saturation after 4 hours.
