Nivel de infección y saneamiento del virus del entrenudo corto (GFLV) en el cv. de vid Pedro Ximenez en la denominación de origen Montilla-Moriles (DOMM)

Abstract

Mediante análisis por test ELISA de hojas de vides (Vitis vinifera L.) del cv. Pedro Ximénez, procedentes de 28 parcelas experimentales distribuidas por la DOMM, se determinó el número de cepas infectadas por el virus del entrenudo corto infeccioso (GFLV). Cinco de las parcelas, no mostraron planta virótica alguna; otras siete, presentaron bajo nivel de contaminación (< 15 %); en otras cinco parcelas, el número de plantas atacadas estuvo comprendido entre el 15 y el 30 %, es decir, ya tuvieron un nivel notable de ataque, y por último, en las 11 parcelas restantes el número de plantas afectadas superó el 30 %, lo que se consideró como un grado de infección muy elevado. No se encontró relación entre el número de cepas viróticas y la edad o la densidad de la plantación, o el tipo de portainjerto empleado. Sin embargo, pudieron establecerse agrupaciones territoriales de parcelas con niveles similares de contaminación, lo que pudo estar relacionado con el uso de material, infectado para realizar los injertos y/o la presencia de Xiphinema index en la zona, como las causas más importantes en la transmisión del virus.
No obstante la variabilidad indicada en cuanto al porcentaje de plantas viróticas, el conjunto de la DOMM se consideró como bastante afectado. Por ello, interesó el saneamiento del material, lo que se logró a nivel del 92 % por cultivo “in vitro” de meristemos. Se observó que la planta saneada creció mejor in vitro que la afectada por entrenudo corto.

A comparative analysis of regions worldwide with Pinot noir

This study examines the growing season climates of selected wine regions worldwide that have significant areas under Pinot noir.

Discovering the process of noble rot: fungal ecology of grape berries during the noble rot transformation in different vineyards of the Tokaj wine region

Botrytis cinerea, a well-known grapevine pathogen, has more than 1200 host plants causing grey rot in grapevine berries. However, it can also result in a desirable phenomenon called noble rot under specific microclimate conditions. An extraordinary demonstration of this natural process can be observed in the creation of aszú wines within Hungary’s Tokaj wine region. Beside B. cinerea other fungi and yeasts are involved in the secondary metabolic development of the grape berry which contributes to the sensory and analytical characterization of noble rot wines.

Application of DEXI PM Vigne sustainability tool to the assessment of alternative vineyard protection strategies

Implementing alternative grapevine systems that incorporate sustainable strategies and innovative farming practices is essential. However, we lack tools for measuring the impact of these new practices on the overall sustainability of vineyards. DEXi PM Vigne (Gary et al., 2015) is a tool developed for ex ante assessment of the sustainability of grapevine cropping systems, from the plot to the farm scale. In the present study, we focused on implementing new strategies of integrated crop protection management with limited pesticide use in vineyards.

What practices in the vineyard lead to the production of wines that consistently win medals?

High quality wines start in the vineyard however little is known about the role vineyard management practices play in this quality outcome. Gold medals and well-known regionality increase consumer preference for purchasing a wine. An increase in the former will certainly also drive an increase in the latter and therefore practices in production that consistently lead to gold medal winning wines will improve both the marketability of the region and its products. It is argued that vinification is the main driver of wine quality and in fact, the presence of some oak compounds is a well-known consumer and expert mark of quality. However, only select wines are vinified in oak and therefore the original grape quality at the winery door must in fact drive all further downstream vinification decisions.

Assyrtiko wines of Santorini produced by different autochthonous yeasts: Differences in aromatic and organoleptic profiles

Different yeasts were isolated from spontaneous fermentation of Assyrtiko grape must in Santorini Island, Greece. Molecular typing revealed the presence of three Saccharomyces cerevisiae strains (S9, S13, S24) and one strain of the yeast species Nakazawaea ishiwadae (N.i). The four isolated strains were further tested in laboratory scale fermentations of Assyrtiko must in pure inoculation cultures and in sequential inoculation (72 hours) of each S. cerevisiae strain with the strain of N. ishiwadae. All fermentation trials were realised in duplicate.
