Abstract The importance of viticulture and the winemaking socioeconomic sector in Europe is largely acknowledged. most famous regions commonly present very specific environmental characteristics, where climate often plays a central role. Furthermore, given strong influence atmospheric factors on this crop, change can significantly affect yield wine quality under future conditions. Trends recorded recent past many viticultural hint at an already pronounced increase growing‐season mean...
The phenolic compounds hydroxycinnamates, anthocyanins, flavonols, and flavan-3-ols of sweet cherry cultivars Burlat, Saco, Summit, Van harvested in 2001 2002 were quantified by HPLC-DAD. Phenolics analyzed at partially ripe stages during storage 15 ± 5 °C (room temperature) 1−2 (cool temperature). Neochlorogenic p-coumaroylquinic acids the main hydroxycinnamic acid derivatives, but chlorogenic was also identified all cultivars. 3-glucoside 3-rutinoside cyanidin major anthocyanins. Peonidin...
Leaf-level morphological and structural adaptations to reduce water loss were examined in five olive ( Olea europaea L.) tree cultivars (Arbequina, Blanqueta, Cobrançosa, Manzanilla Negrinha) growing under field conditions with low availability. Leaf measurements included leaf tissue thickness, stomatal density, area, mass per unit density of tissue, relative content, succulence, saturation deficit, content at cuticular transpiration rate. We found considerable genotypic differences among...
Water relations, leaf gas exchange, chlorophyll a fluorescence, light canopy transmittance, photosynthetic pigments and metabolites fruit quality indices of cherry cultivars 'Burlat', 'Summit' 'Van' growing on five rootstocks with differing size-controlling potentials that decrease in the order: Prunus avium L. > CAB 11E Maxma 14 Gisela 5 Edabriz, were studied during 2002 2003. Rootstock genotype affected all physiological parameters. Cherry grafted invigorating had higher values midday stem...
Plants usually tolerate drought by producing organic solutes, which can either act as compatible osmolytes for maintaining turgor, or radical scavengers protecting cellular functions. However, these two properties of solutes are often indistinguishable during stress progression. This study looked at individualizing osmotic adjustment versus osmoprotection in plants, using cowpea the model species. Two cultivars were grown well-watered soil, conditions, followed rewatering through fruit...
Grapevine varietal suitability is strongly linked to regional environmental conditions and growers tend select varieties that are best suited these conditions. A high agreement between current growing regions optimal climatic zones thus anticipated for a given variety. changing climate is, however, expected impose new challenges this long-term selection. The present research examines the spatial distribution of main grapevine in Portugal, establishing future each locations 44 assessed, their...
SUMMARY Phenological models are considered key tools for the short-term planning of viticultural activities and long-term impact assessment climate change. In present study, statistical phenological were developed budburst (BUD), flowering (FLO) veraison (VER) 16 grapevine varieties (autochthonous international) from Portuguese wine-making regions Douro, Lisbon Vinhos Verdes. For model calibration, monthly averages daily minimum (Tmin), maximum (Tmax) mean (Tmean) temperatures selected as...
Drought, elevated air temperature and high evaporative demand are increasingly frequent during summer in grape growing areas like the Mediterranean basin, limiting grapevine productivity berry quality. The foliar exogenous application of kaolin, a radiation-reflecting inert mineral, has proven effective mitigating negative impacts these abiotic stresses other fruit crops, however, little is known about its influence on composition key molecular mechanisms metabolic pathways notably important...
Extreme conditions, such as drought, high temperature, and solar irradiance intensity, are major factors limiting growth productivity of grapevines. In a field experiment, kaolin particle film application on grapevine leaves was examined during two different summer conditions (in 2012 2013) with the aim to evaluate benefits this practice against stressful hindering photochemical processes. We used chlorophyll fluorescence investigate attached leaves. Two months after application, hottest...
The impact of elevated carbon dioxide concentration ([CO2]) on the quality berries, must, and red wine (with special reference to volatile composition, phenolic content, antioxidant activity) made from Touriga Franca, a native grape variety Vitis vinifera L. for Port Douro manufacturing grown in Demarcated Region Douro, was investigated during 2005 2006. Grapevines were either open-top chambers (OTC) with ambient (365 ± 10 ppm) or (500 16 [CO2] an outside plot. In general, increase did not...
The Iberian viticultural regions are convened according to the Denomination of Origin (DO) and present different climates, soils, topography management practices. All these elements influence vegetative growth varieties throughout peninsula, tied grape quality wine type. In current study, an integrated analysis climate, soil, was performed for DO regions, using state-of-the-art datasets. For climatic assessment, a categorized index, accounting phenological/thermal development, water...
