Morphological image analysis for determining bunch grape characteristics: A case study on bunch weight in Cabernet-Sauvignon
Morphological image analysis is a powerful technique used in various fields, including agriculture, to quantitatively assess the physical characteristics of objects. In viticulture, the accurate assessment of grapevine characteristics is essential for optimizing crop management and improving the quality of wine production.
Identification and evaluation of the winemaking sub-zones of the PDO Amyndeo winegrowing region
Context and purpose of the study. The concept of terroir encompasses the investigation of the physical environment’s influence on grapevine physiology, grape composition, and wine quality, with an emphasis on employing viticultural zoning techniques to systematically characterize and analyze terroirs.
Water retention properties of viticultural calcisols from D. O. P. Valdepeñas (Spain)
A good knowledge of the soil physicochemical properties, as well as its ability to retain and put the necessary water available to the plants, is essential when it comes at the design of an irrigation plan.
Evaluation of new fem grapevine varieties resistant to the main fungal diseases
Context and purpose of the study. The genetic improvement of grapevines at the Edmund Mach Foundation (FEM) has evolved significantly since its inception, and its philosophy on sustainable viticulture through crossbreeding techniques aligns with the urgent need to reduce chemical use in agriculture.
Vegetative propagation during domestication – rooting ability of wild grapevines
The origins of plant propagation trace back to the moment of early humans’ transition from a nomadic existence to settled agricultural societies, cultivating their food.
Advancing wine authentication: non-invasive near-infrared spectroscopy and machine learning for vintage and quality traits assessment
Wine fraud, encompassing counterfeiting and adulteration, poses a significant threat to the wine industry, resulting in annual losses totalling billions of dollars.
Simulating single band multispectral imaging from hyperspectral imaging: A study into the application of single band visible to near-infrared multispectral imaging for determining table grape quality
To be accepted by the market and consumers table grapes need to meet certain requirements in terms of physical and chemical quality parameters.
VineAI: artificial intelligence for fungal disease
Early and accurate grapevine disease detection and surveillance are crucial for optimizing vineyard management practices.
Spectral discrimination between Vitis vinifera and labrusca by spectroradiometric techniques
Brazil is one of the few countries where vineyards of Vitis labrusca and Vitis vinifera coexist in the same geographical spaces, due to complex processes of territorial occupation by successive waves of European settlers.
Impact of sample size on yield estimation in commercial vineyards
The accurate estimation of yield is a fundamental for suitable viticulture, playing a pivotal role in the planning of logistics, the allocation of resources and the formulation of commercial strategies.
Approaches for estimating the age of old vineyards in Campo de Borja
Determining the age of a vineyard is essential for understanding its influence on wine quality and characteristics.
Climate regionalization of Uruguayan viticulture for ecological sustainability
Ecological sustainability refers to developing viticulture in adequate environmental conditions.
Field evaluation of biofungicides to control powdery mildew and botrytis bunch rot of wine grapes in California
Grapevine powdery mildew caused by Erysiphe necator and Botrytis bunch rot caused by Botrytis cinerea are two of the most important fungal diseases in California grape production.
Soil mineral nitrogen dynamics in cover-cropped irrigated vineyards with contrasting soil textures
Context and purpose of the study. Cover cropping in vineyards supports grape yield, quality, and soil health.
Optimizing vine pruning of Pinot noir and Müller-Thurgau after extreme hail damage
Hail damage can have a major impact on the vine’s physiological growth (defoliation, wood and cane damage) and can lead to significant yield and economic losses.
Exploring between- and within-vineyard variability of “Malvasia di Candia aromatica” vineyards from Colli Piacentini
Several studies demonstrated how climate and soil may be key drivers of variability at different scales.
Drip irrigation and precision cooling reduce impact of extreme heat events during berry ripening
Context and purpose of the study. Heatwaves have become more frequent and intense in several winegrowing regions.
Improving grapevine cloning material of Welshriesling by comprehensive analysis
The important grape variety Welschriesling for Austrian and Southeast European viticulture has been selectively bred over the years for improving some quantitative traits. Collected genotypes as well as the local clones were examined from agricultural, analytical, sensory, and genetic perspectives.
Above and below–research challenges for the future of winegrape production
Grapevines interact with the climate (aboveground) and the soil (belowground), affecting the characteristics of winegrapes produced. These interactions are impacted by climate change, the erosion of biodiversity, and losses of soil organic matter (SOM).
PyExpress – A pipeline for fast and reliable UAV image processing in vineyards
Increasing drought poses a challenge to viticulture, with complex impacts on grape yield and quality. The use of Unmanned Aerial Vehicles (UAV) in Precision Viticulture offers a valuable tool to detect drought stress, capturing its spatio-temporal variability and thus, supports management strategies.
