Different nitrogen inputs and/or development under adverse water conditions (water stress/low quality high salinity/electrical conductivity), such as those prevailing in Almeria (Mediterranean coast, south-east Spain), may affect overall fruit and vegetable quality. This study evaluated the influence of salinity reduction hydroponic nutrient solution on strawberry nutritional compounds (Fragaria × ananassa Duch., cv. Primoris).Strawberries obtained treatments recorded highest values for...
The objective of this work was to study the effect shading screens, normally used during day for cooling purposes, on night-time climate unheated greenhouses. For purpose, first a number experimental measurements were taken cold nights characterise greenhouse both with and without an aluminised external screen. Secondly Computational Fluid Dynamic (CFD) model developed. After validation by comparison data, simulate different sky conditions ranging from cloudless overcast nights. Simulations...
Although a large number of pesticides different compositions are regularly used in agriculture, the impact on physiology field crops is not well understood. Pesticides can produce negative effects crop physiology-especially photosynthesis-leading to potential decrease both growth and yield crops. To investigate these greenhouse sweet peppers, effect 20 insecticides 2 fungicides (each sprayed with wetting agent) photosynthesis pepper leaves was analyzed. Among pesticides, nine caused...
The horticultural industry demands high-quality resources to achieve excellence in yield and optimal revenues. Nitrogen is a pivotal nutrient accomplish these goals for plant growth product quality. However, competition water semi-arid regions can force the use of brackish waters, which impair N uptake. lower uptake be due several reasons, such as an antagonism between ions, absence ATP, and/or alteration metabolism. effect supplying NO3- alone or combination with NH4+ , coupled low high...
We investigated the effect of supplying nitrogen, as NO3- or NO3-/NH4+, on composition fruits sweet pepper (Capsicum annuum L. cv. Melchor) plants grown with different CO2 concentrations ([CO2]): ambient elevated (800 μmol mol-1). The results show that application NH4+ and high [CO2] affected chroma related to chlorophylls. Ca, Cu, Mg, P, Zn were significantly reduced in nourished NH4+, loss Fe being more dramatic at increased [CO2], which was also case protein concentration. concentration...
In many plant species, long-term exposure to elevated CO2 concentration results in a reduction photosynthetic capacity, known as acclimation. This process is mainly explained by feedback inhibition mechanism. The supply of fraction the nitrogen (N) nutrient solution NH4+ can play an important role maintenance activity and could mitigate acclimation process. aims present work were study response sweet pepper (Capsicum annuum L.) enrichment Mediterranean greenhouse conditions, throughout crop...
The present study was conducted to determine the mitigating influence of greenhouse CO2 enrichment on negative effects salinity in Mediterranean conditions. Hybrid Raf (cv. Delizia) tomato plants were exposed two levels nutrient solution (5 and 7 dS/m) obtained by adding NaCl, concentrations (350 800 μmol/mol) which applied during daytime according a strategy linked ventilation. Increasing water negatively affected leaf area index (LAI), specific (SLA), use efficiency (WUE), radiation (RUE)...
Abstract Increasing water stress situations were imposed on Schefflera arboricola Hayata ‘Compacta’ for up to 7 days under controlled growth chamber conditions. Net CO 2 exchange and transpiration rates, stomatal conductance vapor xylem potential measured at constant temperature, photosynthetic photon flux density (PPFD), atmospheric humidity. A strong relationship was found process. When the content of substrate decreased as a result soil surface evaporation, both rates drastically. Xylem...
Sweet pepper is susceptible to changes in temperature conditions, especially above 30 °C. In this research study, two cultivars, Melchor and Tamarín, were subjected three different temperatures. For this, the experiment was run at specific temperatures (24 °C, 28 32 °C), keeping rest of parameters same all experiments. fully mature fruits, such as weight, color, TSS, total phenols, mineral content, amino acid content analyzed. Our results showed that high reduced fruit weight increased color...
Abstract The effects of air temperature and leaf-to-air vapor pressure deficit (VPD) on the gas exchange behavior, i.e., net CO 2 rate (NCER) dark respiration rate, transpiration, leaf diffusive conductance to water vapor, use efficiency (WUE), xylem potential Schefflera arboricola Hayata ‘Compacta’ were examined under conditions adequate substrate moisture in a controlled environment growth chamber. optimum for NCER was around 25°C at photo-synthetic photon flux density (PPFD) 450 μmol s -1...
