    This work analyzes the social reproduction strategies of small and medium grape growers located in Luján de Cuyo, Mendoza, Argentina. Small grape growers are involved in a process of continuous "displacement" that corresponds to intra-generational and inter-generational mobility. It is observed that those who were part of the rural middle classes...

    Climate change is affecting viticulture particularly because in wine production most of the value is provided by the desired tipicity. High air temperatures decouple grape sugars and anthocyanins accumulation impacting negatively wine composition. In this trial, carried out under the temperaturewarm and semi-arid conditions of eastern Spain, we as...

    For the west of Argentina, vitiviniculture represents the main agricultural industry. In the irrigated valleys where viticulture is developed, the problems of salinity and toxicity of some ions in the soil limit productivity and quality of the obtained products. The tolerance to toxic ions (Cl-, Na+, B (OH)4-) of the commercial grape cultivars is ...

    The effect of grapevine age on growth and berry development was studied from 2014 to 2016 on an experimental vineyard managed by the Hochschule Geisenheim University in Geisenheim, Germany. The vineyard was initially planted in 1971 with Vitis vinifera (L.) cv. Riesling grafted on 5C Teleki. In 1995 and 2012, several rows were uprooted and replant...

    This work starts from the idea that the nitrogen application in pre-harvest would have positive effects on biomass accumulation of the vine plant before its winter rest, and that would enable a better and faster sprouting in the following season, without sacrificing the oenological quality of the grapes. In a malbec vineyard located in El Peral, T...

    Young vines are very susceptible to frost damage due to their short height which situates frost-sensitive buds and shoots very close to the ground, which is where the coldest air temperatures typically occur. Farmers often use grow tubes to protect young vines from damage by animals and herbicides, but the potential benefit for protecting vines fr...
