The effect of post-harvest defoliation on carbon resources of high yielding Sauvignon blanc grapevines
We wanted to quantify the importance of post-harvest carbohydrate assimilation to replenish vine reserves, additional to maintaining optimal growth, productivity and fruit quality of high yielding vigorous Sauvignon blanc grapevines.
Different thermal environment during dormant season lead to a differential cold hardiness status in Vitis vinifera cv. Malbec–The experience in Mendoza, Argentina
En Vitis sp., la resistencia al frío (RF) adquirida durante la estación de dormición (ED) es crucial para la supervivencia y el rendimiento. La mayoría de la información sobre RF es obtenida en áreas cercanas a 40°N, donde las temperaturas causan daños recurrentes en viñedos.
What does the functional-structural plant model hydroshoot tell us about the reasons for grapevine (Vitis vinifera L.) photosynthesis depression?
Grapevine is a species that get along with water deficit. Yet, it cannot always stand thirst when accompanied by high temperatures, reducing noticeably its gas-exchange rates. Elucidating the origins of this reduction is a challenge, regarded the complex hydraulic, biochemical and energy processes lying behind gas-exchanges.
Heat berry: the influence of abiotic factors on the composition of berries, must and wine in Vitis vinifera L. cv. Riesling
It has been known for a long time that altering microclimate affects fruit composition and wine quality. The research project Heat Berry focuses on future scenarios of the climate change regarding higher temperatures and the risk of increasing sun radiation to the fruit. Field experiments were conducted in 2015 and 2016 at an experimental site at Geisenheim (Germany) using Riesling (clone 198-25 grafted to rootstock SO4).
Effect of ethephon application on grape ripening and wine quality during two years
Ethephon is known to be a growth regulator that, when applied to the plant, is metabolized into ethylene. In this study, it has been evaluated the foliar application at the beginning of veraison of a commercial product (Fruitel 180, 18% w/v ethephon) in a Vitis vinifera L. cv. red Tempranillo vineyardin La Rioja (north of Spain).
Evaluation of different tools to measure water status in vines (Vitis vinifera L.) with cv. Tempranillo blanco
Different irrigation treatments were applied in vines (Vitis vinifera L.) with cv. Tempranillo blanco during 2016 in an experimental field located in Rincón de Soto (La Rioja, Spain), 42°12'37"N; 1°52'36"W.
Preliminary results of the eliminary results of the characterizarion of Argentine wines and the foreseeing of the future effects of global warming on the quality and style
The few studies that relates the chemical composition and the organoleptic characteristics of Argentine wines with the origin show that climate is a very important factor.
Assessing the use of shading to mitigate degradation of grape metabolic content in warm climates
Global warming, and the ongoing expansion of viticulture to marginal areas is increasing the surface area of vineyards experiencing high solar irradiance and daily temperatures, leading to the loss of quality-related compounds.
Combined effects of drought and high temperature on gas exchange and growth of Malbec grapevines
Drought and high temperature are important threats to plant growth and sustainable agriculture worldwide.
