Photosynthesis and carbohydrate dynamics are highly affected by abiotic stresses, making them a target to be studied in a context of fluctuating and constraining environment.
In viticulture, the timing of phenology is critical to optimize grape quality potential particularly so in cool climates. Flowering and veraison are key phenological stages for grapevines.
Grape quality is a complex concept that refers to the simultaneous achievement of optimal levels in many parameters, thus single berry attributes data are not adequate to define grape suitability for a specific end use.
The aim of this study was to validate and implement different non-destructive methods of leaf area and leaf area index (LAI) determination in VSP trained grapevines (Vitis vinifera L. cv. Riesling) in a field trial comparing different management systems (i.e. integrated (GAP) and two different organic (European Union Regulation 834/07) management systems).
The measurement of leaf water potential has been used to monitor the water relations of grapevines since the development of the pressure chamber.
The aim of this study was to investigate the effect of leaf removal during two developmental stages on the compositional development of white Riesling (Vitis Vinifera L.).
In Spain, grapevines were traditionally cultivated under rainfed conditions until recent years. In Galicia, the need for irrigating the vineyards was not a priority until very recently.
Spectral parameters as the NDVI (Normalized Difference Vegetation Index) are helpful to monitor developing stages in vegetation, including the detection of water stress in vineyards.
A model of the developing berry was constructed with data from published studies as well as 13 varieties grown in Davis, CA (USA).
Identify and trace unambiguously the wine plants before and after planting is a key activity to give the buyer a guarantee of buying or using a certified plant.
This study aimed to determine and compare the vertical root system distribution of the regional vine cultivar Loureiro, once grafted on ten different rootstocks.
