Geostatistical solutions based on open-source GIS in support of harvest planning for mountain vineyards

Abstract

Geographical information systems (GIS) offer an important tool to support grape-growers’ decisions, allowing for visualization in an adequate geographical support of information on the behaviour of his vineyards. However, commercial GIS solutions are usually beyond the reach of the average grape-grower, both because of their cost and because of the training needed to master it. In this work we tested a project developed in available open-source GIS software (Quantum GIS) as an application to map grape maturation, and perform map algebra routines in support of harvest planning in mountain vineyards with high complexity and diversity as it is the usual case in the Douro Wine Region. Obtained results confirm the high potential value conferred by grape quality geodata treatment in organizing and planning the harvest, as it improves the flow of information between viticulture and oenology professionals: a maturation precocity index was created demonstrating a spatial structure in its variability. Ways of using that knowledge for harvest scheduling and adjusting sampling sites for maturation control were discussed.

Effects of grapevine leafroll associated virus 2 infection on leaf net photosynthesis, yield and berry quality in Vitis vinifera cv. Malbec

Grapevine leafroll associated virus 2 (GLRaV-2) is one of the most common damaging viral diseases in vines, causing significant reductions in photosynthesis, yield and grape quality. In this study, we tested the hypothesis that the leaf net photosynthesis and the transport of sugars to the berries is progressively reduced along the season in vines infected with GLRaV-2, and consequently, the yield (kg per plant) and total soluble solids (TSS) at the berry harvest-ripe stage are lower than non-infected vines.

Influence of genotype and water availability on respiratory costs and plant carbon balance in grapevines (Vitis vinifera L.)

Due to the important contribution of agriculture to the global carbon dioxide (CO2) balance, new techniques are currently being developed to accurately estimate the carbon balance of different crops. Field studies to date in grapevines have been based on carbon allocation and biomass accumulation dynamics.

Phenological behavior and evolution of maturation of grapes of juice preparation

The ripening level of the grape is one of the most important factors in the quality of its derivatives, because of the complex phenomena inherently related to the varieties and environmental conditions. The objective of the present study was to monitor the phenological development of the Chardonnay variety and to evaluate the influence of the different ripening points on the production of juices.
