Evaluation of state of vineyards and characterization of vineyard sites of the integrated area of Tokaj Kereskedőház ltd. in Tokaj region

Abstract

The Tokaj Kereskedőház Ltd. is the only state owned winery in Hungary. The company is integrating grapes for wine production from 1100 hectares of vineyard, which consist of 3500 parcels with average size of 0,3 hectares, owned by about 500 families of the region. The vineyards are unevenly spread in total 27 village of Tokaj region. 

The aim of our study was to determine the state of vineyards of each single parcel of the integrated area, and the characterization of the ecology of the vineyard sites. Based on the information collected a site-specific vineyard design and cultural practice could be achieved on the given territory. 

The state of vineyards, concerning variety, training system, trellis system, row and vine spacing, row orientation, and production characteristic was determined by visual inspection of every single parcel. Airborne hyperspectral imagery was taken, covering the whole Tokaj Wine Region. High-resolution spectral-spatial geodata were captured and analyzed to focus on variety determination, evaluate biophysical properties (NDVI, LAI, Red Edge Position), canopy continuity, structure and identify row anomalies. 

The characterization of vineyards sites was accomplished based on large-scale determination of topography, soil and meso- and macroclimate variables covering the total 11000 hectares planted and potential vineyard land area of Tokaj Region. According to soil survey Digital Optimalized Soil Related Maps and Information Method was taken to produce the proper thematic data layers in 25 m spatial resolution. Results of surveys are analyzed and managed in a geographical information system designed for the project. 

The methods applied during the data collection and analysis will be detailed, while the preliminary results of the state of vineyard and the characterization of vineyard sites will be demonstrated.

White grape must processed by UHPH as an alternative to SO2 addition: Effect on the phenolic composition in three varieties

The quantity and distribution of polyphenols in musts play a fundamental role in the white winemaking. This is because these substances are exposed to oxidation reactions, which are catalysed by the polyphenol oxidase (PPO), leading to a decrease in the quality of the wines produced. PPO is inactivated by SO2, but currently, due to the restrictions of the legislation, other methodologies are being investigated. Ultra-High Pressure Homogenization (UHPH) is a non-thermal physic technology that exerts an ultrahigh pressure pumping (>200 MPa) of a fluid through a valve in a continuous system.

Perception, liking and emotional response of tropical fruit aromas in Chardonnay wines

Tropical fruit aromas in wines are thought to be important to wine consumers, although there is little research to confirm this statement. With so many wine styles available, it has become important to understand the qualities that are desirable to consumers and how to achieve those qualities. Thiols and esters are compounds that have been found to cause tropical fruit aromas in chardonnay (ref). Fermentation temperature gradients and skin contact were found to increase these compounds using micro scale fermentations. This work aimed to scale up these fermentations/operations to determine if the desired tropical fruit aromas could still be achieved and if there is a perceivable difference in tropical fruit aromas, liking, and emotional response in the wines at the consumer level.

Integrated approaches for the functional characterization of miRNAs in grapevine

Micro(mi)RNAs are small non-coding RNAs that regulate several pathways and are widely recognised as key players in plant development, tissue differentiation, and many other important physiological processes, including plant adaptation to biotic and abiotic stresses. The release of plant genomes and the application of high throughput sequencing have considerably extended miRNA discovery across many species, including grapevine (Vitis spp.). Despite their relevance in plant development, functional studies in grapevine to clarify the function of miRNAs are not yet available. Through the grapevine genetic improvement platform IMPROVIT at CNR-IPSP (http://www.ipsp.cnr.it/en/thematics/turin-headquarter-thematics/improvit/), we developed integrated approaches to discover miRNA function in grapevine.
