Agronomic and qualitative behaviour of cv. Tempranillo according to three vine spacing on two different hydric-edaphic situations in the Duero river valley

Abstract

The knowledge of the influence of soil conditions on the effects that different plant densities provoke in the agronomic grapevine behaviour becomes very interesting since it allows to focus the vineyard management on the optimization of the natural, hydric and human resources.
This work is focused on the study of the vegetative, productive and qualitative behaviour of Tempranillo variety distributed with three different distances between vines (1.2, 1.5 and 1.8 m) and a common distance between rows (3.0 m) along the period 2005-2007, in two different growing conditions, moderated deficit irrigation and non irrigation. The final objective is to know the more adequate plant density under each particular growing conditions. The experimental trials have been located in the A.O. Rueda, along the Duero river valley, in the province of Valladolid (Spain).
The different vine spacing treatments have shown some differences in pruning weight, vigour of shoot, yield per hectare and cluster weight in both hydric-edaphic situations, being these differences more remarkable in the non irrigation conditions. The differences between treatments in fertility and berry weight have been fewer. The grape quality has hardly shown any difference between treatments in both growing situations.
These results suggest the convenience of different vineyard management depending on the particular growing conditions, being of doubtful effectiveness the increase of the number of plants if there is no any limiting factor that substantially alters these growing conditions.

Environmental and viticultural practice effects on the phenolic composition of grapes: impact on wine sensory properties

Grape phenolic compounds are located in the internal layers of grape skins and seeds. They are synthesized via the phenyl-propanoid biosynthetic pathway which is modulated by both biotic and abiotic factors.

Yeast Derivatives: A Promising Alternative In Wine Oxidation Prevention?

Oxidation processes constitute a main problem in winemaking. Oxidation result in color browning and varietal aroma loss, which are key attributes of wine organoleptic quality [1]. Despite the mechanisms involved in wine oxidation have been extensively reviewed [2], the protection of wine against oxidative spoilage remains one of the main goals of winemaking.
SO2 is one of the most efficient wine antioxidants used to prevent oxidation and microbial spoilage. However, intolerances caused by SO2 have led to the reduction of its concentration in wines.

Development and validation of a free solvent UHPLC/MS-MS method to analyse melatonin and its precursors in Spanish commercial wines  

Melatonin is a bioactive compound present in foods and beverages such as wines. During alcoholic fermentation, yeast transforms tryptophan into certain indole compounds, including melatonin. This paper aims to develop and validate a free solvent analytical method by ultra-high performance liquid chromatography coupled with high resolution mass spectrometry (UHPLC/MS-MS) to determine melatonin and its precursors (L-tryptophan, tryptamine, serotonin, tryptophol, N-acetylserotonin, 5-hydroxytryptophan, and 3- indoleacetic) that appropriately prevent the matrix effect.

Viticultura protegida: uso de mallas sombreadoras fotoselectivas como una herramienta para enfrentar la crisis climática en uva de mesa en el norte de Chile

The production of table grapes in Chile is of great importance, being one of the main established fruit crops with over 43,000 hectares distributed across a diverse climate range, from the southern limit of the Atacama desert to the mediterranean zone. Chile is also one of the leading exporters of table grapes. producers must confront the challenges posed by the climate crisis, such as decreased rainfall, increased heatwaves, and extreme temperature events during the growing season, mainly associated with desertification in northern Chile (Atacama and Coquimbo regions).
