Zonificación vitícola y aplicación a la D.O. Montilla-Moriles, usando como referencia la variedad ‘Pedro Ximenes’

Abstract

Se señalaron 28 parcelas, en la zona de D.O. Montilla-Moriles, repartidas por toda la superficie de viñedo, de ellas 12 se localizan en las Zonas de calidad Superior, en los términos municipales de Montilla, Moriles y Aguilar de la Frontera.
En cada una de las parcelas se realizaron calicatas para el análisis del suelo, y junto a las calicatas se marcaron unas 16 cepas, teniendo especial cuidado en que todas las cepas marcadas pertenecieran a la variedad ‘Pedro Ximenes’.
En primer lugar se tomaron datos correspondientes a factores geo-edáficos y climáticos. Así se realizó una caracterización térmica, heliométrica, hídrica de los diferentes puntos señalados. Igualmente se determinaron diversos índices bioclimáticos. A la vez se llevó a cabo una caracterización geológica y edafológica de los suelos señalados.
En lo que se refiere al material vegetal, se tomaron datos de su estado sanitario, del contenido en macro y microelemnetos de las hojas, de la cantidad y calidad de la cosecha, determinada ésta última por los caracteres del mosto, pH, azúcares y ácidos.
Los resultados del presente año indican:
a.  Respecto al estado sanitario del material vegetal, aproximadamente el 70% de las parcelas estudiadas se encuentra libre de GFLV. La mayor concentración de cepas afectadas corresponde a las zonas de calidad superior.
b.  En general se aprecia un mayor contenido de K en las hojas procedentes de cepas cultivadas en zona de calidad. Los valores de N variaron entre un máximo de 3.20% de m.s. y un mínimo de 2.52%. Por su parte el P varió entre 0.22% máximo y 0.13% mínimo. En lo que se refiere al K, en general, sus niveles han sido altos en toda la zona, destacando, como ya se ha señalado los resultados de la zona de calidad superior. En el trabajo se analizan los resultados obtenidos con todos los oligoelementos estudiados.
c.  Como era de esperar, los contenidos en sólidos solubles fueron más altos en las muestras procedentes de las zonas de calidad superior. En cualquier caso y en el primer año los contenidos en sólidos solubles han sido muy altos en prácticamente todas las zonas muestreadas.
d.  La cosecha ha presentado, este primer año diferencias muy acusadas, debidas a las específicas condiciones climáticas de esa campaña, que han propiciado severos ataques de mildiu y heladas en diferentes áreas.

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

The impact of leaf canopy management on eco-physiology, wood chemical properties and microbial communities in root, trunk and cordon of Riesling grapevines (Vitis vinifera L.)

In the last decades, climate change required already adaptation of vineyard management. Increase in temperature and unexpected weather events cause changes in all phenological stages requiring new management tools. For example, defoliation can be a useful tool to reduce the sugar content in the berries creating differences in the wine profiles. In a ten-year field experiment using Riesling (Vitis vinifera L, planted 1986, Geisenheim, Germany), various mechanical defoliation strategies and different intensities were trialed until 2016 before the vineyard was uprooted. Wood was sampled from the plant compartments root, trunk, cordon and shoot for analyses of physicochemical properties (e.g. lignin and element content, pH, diameter), nonstructural carbohydrates and the microbial communities. The aim of the study was to investigate the influence of reduced canopy leaf area on the sink-source allocation into different compartments and potential changes of the fungal and prokaryotic wood-inhabiting community using a metabarcoding approach. Severe summer pruning (SSP) of the canopy and mechanical defoliation (MDC) above the bunch zone decreased the leaf area by 50% compared to control (C). SSP reduced the photosynthetic capacity, which resulted in an altered source-sink allocation and carbohydrate storage. With lower leaf area, less carbohydrates are allocated. This for example resulted in a decreased trunk diameter. Further, it affected the composition of the grapevine wood microbiota. SSP and MDC management changed significantly the prokaryotic community composition in wood of the root samples, but had no effect in other compartments. In general, this study found strong compartment and less management effects of the microbial community composition and associated physicochemical properties. The highest microbial diversities were identified in the wood of the trunk, and several species were recorded the first time in grapevine.

Short-term relationships between climate and grapevine trunk diseases in southern French vineyards

Mesoclimate impact on Tannat in the Atlantic terroir of Uruguay

The study of climate is relevant as an element conditioning the typicity of a product, its quality and sustainability over the years. The grapevine development and growth and the final grape and wine composition are closely related to temperature, while climate components vary at mesoscale according to topography and/or proximity to large bodies of water. The objective of this work is to assess the mesoclimate of the Atlantic region of Uruguay and to determine the effect of topography and the ocean on temperature and consequently on Tannat grapevine behavior.

Phenological characterization of a wide range of Vitis Vinifera varieties

In order to study the impact of climate change on Bordeaux grape varieties and to assess the adaptation capacities of candidates to the grape varieties of this wine region to the new climatic conditions, an experimental block design composed of 52 grape varieties was set up in 2009 at the INRAE Bordeaux Aquitaine center. Among the many parameters studied, the three main phenological stages of the vine (budburst, flowering and veraison) have been closely monitored since 2012. Observations for each year, stage and variety were carried out on four independent replicates. Precocity indices have been calculated from the data obtained over the 2012-2021 period (Barbeau et al. 1998). This work allowed to group the phenological behaviour of the grapevine varieties, not only based on the timing of the subsequent developmental stages, but also on the overall precocity of the cycle and the total length of the cycle between budburst and veraison. Results regarding the variability observed among the different grape varieties for these phenological stages are presented as heat maps.
