A predictive model of spatial Eca variability in the vineyard to support the monitoring of plant status

Abstract

In a vineyard, plant water status variability is strongly dependent on soil spatial variability, whose physical characteristics drive the processes involved in the soil water balance. More the soil and its characteristics vary in space (horizontally and vertically), more the productive and qualitative vine performances will be non-homogeneous. In this context, the proximal sensing of apparent soil Electrical Conductivity (ECa) and its monitoring during the growing season can help to understand the nature of spatial variability of vineyard, supporting both viticultural microzoning (identifying Homogeneous and functional Homogeneous Zones, HZs and fHZs) and field experiments. The aims of this contribution are: i) to show how the use of proximal sensing of ECa in the identification of HZs is important, (ii) to show the added value of ECa monitoring during the growing season in order to identify the fHZs, (iii) and to highlight its importance in the evaluation of the experimental field treatments results in vineyard. The study was carried out in two rainfed commercial vineyards located in the southern Italy (Campania Region) cultivated with Greco (white) and Aglianico (red) grapevine variety. Over 2020 and 2021 seasons, detailed soil and atmosphere parameters were recorded, in-vivo plant eco-physiological monitoring has been conducted, and vine status spatial variability monitored by means of UAV multispectral images. Apparent soil electric conductivity (ECa) was measured five times for each vineyard during the growing season 2021 by using the PROFILER EMP 400 electromagnetometer both in vertical and horizontal dipole mode. This instrument allows to simultaneously work with three frequencies (5000, 10000 and 15000 Hz) and explore different depth of sub-soil. The recorded data were processed in MATLAB and compared with other recorded variables within GIS environment. The results have shown how the ECa can be a carries of information to support viticultural microzoning and experimental field data analysis.

Influence of methyl jasmonate foliar application to vineyard on grape volatile composition over three consecutive vintages

An alternative to improve grape quality is the application to the vineyard of elicitors. Although these compounds were first used to increase resistance of plants against pathogens, it has been found that they are also able to induce mechanisms involved in the synthesis of phenolic compounds and some amino acids. However, researches about the influence of elicitors on grape volatile composition are scarcely. Therefore, the aim of this work was to study the influence of methyl jasmonate (MeJ) foliar application on grape aroma composition over three consecutive vintages. MeJ was applied to Tempranillo grapevines at a concentration of 10 mM in 2013, 2014, and 2015 years. Control plants were sprayed with water.

Impact of crop load management on terpene content in gewürztraminer grapes

Context and purpose of the study ‐ Crop load management by cluster thinning can improve ripening and the concentration of key metabolites for grape and wine quality. However, little work has been done on testing the impact of crop load management on terpene content of white grapes. The goal of the study was to assess if by reducing crop load via cluster thinning growers can increase terpene concentration of grapes, as well as to test if the timing of thinning application affects terpene concentration.

Novel contribution to the study of mouth-feel properties in wines

In general, there is a well-established lexicon related to wine aroma and taste properties; however mouth-feel-related vocabulary usually includes heterogeneous, multimodal and personalized terms. Gawel et al.
(2000) published a wheel related to mouthfeel properties of red wine. However, its use in scientific publications has been limited. The authors accepted that the approach had certain limitations as it included redundant and terms with hedonic tone and some others were absent. It is of high interest to generate a mouth-feel lexicon and finding the chemical compound or group of compounds responsible for such properties in red wine. In the present work a chemical fractionation method has been developed.
