Monitoring early rooting behavior of grapevine rootstocks: a 2D-imaging approach

Abstract

The plasticity of grapevines in response to diverse growing conditions is influenced, among other factors, by the extent to which the roots explore the soil and the ability to accumulate and retrieve water and nutrients.

Newly planted grapevines, in particular, face challenges due to limited resources. The young plant’s ability for a fast and intensive penetration of the soil is vital in periods of water scarcity. The selection of an appropriate, site-specific rootstock significantly impacts both, the quality of the fruit produced and the economic success of the wine estate. This underscores the importance of providing guidance and recommendations to winegrowers, enabling them to make informed decisions about the selection of suitable planting materials. Despite its critical significance, there is very limited information available on the early rooting behavior of commercial rootstocks. Observing below-ground growth poses challenges, but the use of rhizoboxes has proven effective in investigating root-related issues across different species.

Therefore, we established a semi-automated platform using RGB imaging to monitor the root development of three commercial grapevine rootstocks and characterize root architecture parameters including maximal rooting depth and the area colonized by roots. The image processing method enables a rapid batch analysis, yielding reliable data that is highly comparable to the manually assessed reference dataset. This approach serves as a valuable framework for future evaluation of the assertiveness of commercial grapevine rootstocks under challenging planting conditions.

INVESTIGATING TERROIR TYPICITY: A COMPREHENSIVE STUDY BASED ON THE AROMATIC AND SENSORIAL PROFILES OF RED WINES FROM CORBIÈRES APPELLATION

Volatile compounds play a significant role on the organoleptic properties defining wines quality. This particular role was exploited in several studies with the aim to differentiate wines from a more or less extensive production area, according to their sensory profile [1], as well as their chemical composition [2,3] (Di Paola-Naranjo et al., 2011; Kustos et al., 2020). Indeed, since aroma compounds development in grapes depends primarily on the environmental conditions of the vines and grapes (soil and climate), it is conceivable that these parameters craft the aromatic signature of the wine produced, in relation to its origin (Van Leeuwen et al., 2020). In this work, a general study on the aromatic and sensorial profile of wines produced in five sub-regions of the Corbières denomination, a renowned red grape varieties viticultural region in South France, was reported.

Un siècle de publications et d’archives de l’OIV : un patrimoine mondial de valeur universelle exceptionnelle pour les sciences et techniques de la vigne et du vin

In 2004, at its general assembly, the oiv adopted the transfer of its scientific and technical heritage from the office to the international organisation of vine and wine. Unesco defines heritage as “our legacy from the past, what we live with today, and what we pass on to future generations.”

Interaction Between Armenian Clay-based Ceramic and Model Wine

Clay-based ceramic vessels (jars, pyhtoi, etc.) for wine fermentation and aging processes have been used in several cultures for millennia. This know-how still in practice in several countries of the Armenian highland is gaining worldwide in curiosity, popularity, and interest. Ceramic pots are famous among traditional winemakers for their benefits such as temperature regulation, natural cooling system, favorable oxygen exchange, and impact on pH, which are different from those of stainless steel, wood barrels, or concrete.

NEW TREATMENTS FOR TEMPRANILLO WINES BY USING CABERNET SAUVIGNON VINE-SHOOTS AND MICRO-OXYGENATION

Toasted vine-shoots as enological additive represents a promising topic due to their significant effect on wine profile. However, the use of this new enological tool with SEGs varieties different than wine and combined with others winemaking technologies, such as micro-oxygenation (MOX), has not been studied so far, despite this combination could result in wine with high chemical and organoleptic quality.
