The responses of two red grape varieties, Bovale Grande (syn. Carignan) and Cannonau Grenache), to temperature natural UV radiation were studied in a three-years field experiment conducted Sardinia (Italy), under Mediterranean climate conditions. Vines covered with plastic films different transmittances compared uncovered controls. Light intensity spectral composition at the fruit zone monitored berry skin was recorded from veraison. Total anthocyanin content (TSA) indicated positive but...
Maximizing water use efficiency, yield, and plant survival under drought is a relevant research issue for almond-tree-growing areas worldwide. The intraspecific diversity of this species may constitute valuable resource to address the resilience productivity challenges that climate change poses crop sustainability. A comparative evaluation physiological productive performance four almond varieties: 'Arrubia', 'Cossu', 'Texas', 'Tuono', field-grown in Sardinia, Italy, was performed. great...
The contribution of light and thermal conditions to berry anthocyanin accumulation was investigatedin grapevine Vitis vinifera L. cv. Cannonau/1103P subjected different irrigation strategies in Sardinia,Italy 2009. In two the deficit treatments root system received 50% 25% cropevapotranspiration (ETc), referred as DI50 DI25, respectively. third treatment, whichincluded partial root-zone drying (PRD), ETc set at 50%. All three were compared a fullirrigation control (FI), thus 100% ETc....
The effect of deficit irrigation strategies on physiological performance, growth, source:sink balance, water productivity and berry composition field-grown grapevines flhis vinifera L. cv.Cannonau (syn.Grenache)/1103P were investigated in Sardinia, Italy, 2009.In two the treatments, both sides root system received 50% 25% crop evapotranspiration (ETc), referred to as DI50 DI25, respectively.In third treatment, which included partial root-zone drying (strategy PRD), ETc was set at 50%.All...
Background and Aims Plant responses to solar radiation are difficult quantify due interannual weather variation interference by other environmental factors. This study assesses the extent of effect UV sunlight on accumulation partitioning anthocyanins in berry skin two red grape cultivars. Methods Results Ultraviolet screening treatments, visible + UV-A visible, applied Bovale Grande (syn. Carignan) Cannonau Grenache) field-grown vines, Sardinia, Italy, promoted a significant difference...
Background and Aims Under natural conditions the grapevine has shown different growth physiological responses to high UV radiation. We evaluate effect of reduced UV-B, UV-A photosynthetically active radiation (PAR) on vine growth, status berry composition in Bovale Grande (syn. Carignan) Cannonau Grenache) field-grown grapes. Methods Results During two seasons trial, UV-screening treatments Visible + Visible, imposed with plastic tunnels from pea size onward, promoted a significant...
Wildland fires represent a major threat to Quercus suber L. ecosystems, which provide relevant socioeconomic and ecological services in the Mediterranean Basin. In this work, we analyzed recent wildland fire dynamics cork oak woodlands along fire-prone areas of Sardinia (Italy), Corsica (France) Catalonia (Spain). We first characterized geographic extent main characteristics these regions how environmental (climate elevation) factors (population land uses) vary covered by then evaluated...
Advantages of vineyard cover crops include soil conservation, nutrient and water cycling, a better growth–yield balance. They naturally promote agro-system biological multifunctionality, biocenosis, pest control. However, for the role on disease control, there is still lack information. We performed systematic evaluation management effects development two main pathogens: Plasmopara viticola Erysiphe necator. Conventional tillage was compared to grass legume during three-season trial in Nurra...
The photosynthetic and photochemical adaptation of grapevine leaves to high UV radiation, under hot dry summer conditions, was investigated in near-isohydric Cannonau (syn.Grenache) nearanisohydric Bovale grande (syn.Carignan).From pea-size stage until harvest, vines with mild moderate water deficit were subjected UV-blocking treatment (-UV) compared a control exposed sunlight (C).Canopy light thermal microclimate, growth density, maximum leaf gas exchange, primary photochemistry (PSII)...
We propose an index for proximal detection of water requirements to optimize the use resources in arid and semi-arid wine growing regions. To test accuracy representativeness proposed irrigation need (IIN), plant status physiological performances were monitored during seasons 2019 2020 two grapevine varieties with different anisohydric degree (Vermentino Cannonau) grown 3 sites Sardinia (Italy). Daily leaf gas exchange curves stem potential recorded. Canopy temperature was monitored, using...
Environment has a great impact on berry composition. In this context we investigated the quality of extremely widespread grape varieties in Sardinia, cvs. Cannonau, Bovale sardo and Monica, cultivated at different altitudes. The work was conducted two-year period two vineyards located respectively 500 700 meters above sea level. Viticultural model cultivation practices were same for both vineyards. following measurements noted: (i) main phenological phases, (ii) yield its components, (iii)...
The influence of light and thermal microclimate on berry quality a Vermentino vineyard, managed with deficit irrigation strategies in north-western Sardinia, was analyzed. Two water deficit, pre- (ED) post-veraison (LD), an (IC) non-irrigation (NC) control treatments were compared during development. Grapevine performances evaluated by analyzing leaf gas exchange, source-sink balance, effects composition. Early and/or late following mild to moderate stress threshold enabled high...
The genetic basis of plant response to light and heat stresses had been unveiled, different molecular mechanisms leaf cell homeostasis keep high physiological performances were recognized in grapevine varieties. However, the ability develop stress tolerance strategies must be further elucidated since morpho-anatomical traits involved may vary with genotype × environment combination, intensity, duration. A 3-year experiment was conducted on potted plants Sardinian red cultivars Cannonau (syn....
The study of biodiversity is fundamental importance in the context environmental protection and eco-sustainable agriculture management. Its preservation has a key role an extraordinary not only for potential gene pools, which essential selection breeding programs, but also because local varieties are expression territory therefore reflect culture, knowledge, tradition heritage. In this paper, 27 cherry collected different areas Sardinia were characterized described from perspectives,...
<p>The wine market is increasing in economic importance, so it crucial for producers to be competitive, efficient, and productive. In addition, climate change requires the adoption of adaptive strategies a more efficient management natural resources. Especially semi-arid regions, limitation water availability crop farming aiming optimize productivity. Knowing optimal moment irrigation amount apply essential information deficit grapes.
