Abstract A long‐term field experiment was conducted to determine the effect of additions urban waste compost on physical and chemical properties enzymatic activities in a calcareous soil (Fluventic Xerochrept). Total porosity (pores >50 µm measured thin sections from undisturbed samples by image analysis) greater plots treated with than control due larger amount elongated pores. In amended total humified organic C, Pb, Cu, Zn showed significant increase compared nonamended plots....
The contents of total Se and inorganic organic species, as well the proteins, chlorophylls, carotenoids, phenolic acids, were measured in 10-day old sprouts rice ( Oryza sativa L.) obtained with increasing levels (15, 45, 135, 405 mg L-1) sodium selenite selenate distilled water control. Increasing increased sprouts, content especially their soluble conjugated forms. Moderate (i.e., not higher that 45 appeared best compromise to obtain high acid yields together proportion while limiting...
Maize (Zea mays L.) requires water and minerals to grow develop its organs. Its production distribution is highly rainfall-dependent yet current global climatic changes reveal irregular rainfall patterns that result in stress conditions with loss of yield productivity around the world. It well known low availability leads plant adopt a number metabolic alterations overcome or reduce effects. To this end, selenium (Se), trace element, can help limit damage caused by overproduction reactive...
Abstract Salinity poses a significant challenge to global crop productivity, affecting approximately 20% of cultivated and 33% irrigated farmland, this issue is on the rise. Negative impact salinity plant development metabolism leads physiological morphological alterations mainly due high ion concentration in tissues reduced water nutrients uptake. Common bean ( Phaseolus vulgaris L.), staple food accounting for substantial portion consumed grain legumes worldwide, highly susceptible salt...
Abstract A soil column study was conducted to assess the vertical movement of certain heavy metals in soils amended with urban waste compost (90 t ha −1 ). The effect complexing capacity water soluble organic matter from on metal mobility has been previously reported. results this investigation demonstrate enhanced levels Cu, Zn, Ni, and Cr eluted 50‐cm columns when is added a Fluventic Xerochrept clay‐loamy, mixed, mesic Typic Xerochrept, fine sandy‐loamy, mesic. increase these...
Selenium (Se) as an antioxidant is a trace element essential to wellness and the maintenance of human health. Although it has not been confirmed be micronutrient in higher plants, there increasing evidence its benefits plants which inhibits detrimental effects environmental stressors, while only few studies refer action on pollen germination. enhances stress tolerance regulating production quenching reactive oxygen species (ROS); however, endogenous ROS are cross-talk between stigma promote...
This work aimed to investigate the effect of selenium (Se) and irrigation on grain yield, forms Se, phenols, carotenes, some antioxidant activities maize (Zea mays L.) grains. To reach this goal, a 2 year experiment was undertaken. Maize fertigated with sodium selenite at rate 200 g Se ha–1 grown under two water regimes. While did not show clear selected parameters, fertigation increased contents inorganic organic forms, xanthophyll, salicylic acid. Furthermore, while decreased...
Foliar fertilization with selenium (Se) may well be beneficial in increasing the nutritional and qualitative values of food Se-deficient regions such as Mediterranean Basin, contribute to an increase drought resistance plants. The present study has considered detachment force, flesh firmness, pigmentation, fresh dry weight, oil content olive drupes from Se fertilized orchards (Olea europaea L.) under stress well-watered conditions. This also evaluated total Se, amino acid, phenol, carotenoid...
Extra-Virgin Olive Oil (EVOO) is a fundamental component of the Mediterranean diet and it may contain several anti-oxidant substances, such as phenols. Previous research has shown that this food be enriched in phenols by spraying sodium-selenate solution (100 mg L-1 Se) onto crop canopy before flowering. The aim was to evaluate effect Se-fertilization flowering (cv. Leccino) on phenolic profile EVOOs, test what extent effects depend weather pattern, observed two contrasting experimental...
A spectroscopic study was carried out to determine the changes in composition of dissolved organic matter (DOM) a soil repeatedly amended with municipal waste compost. In addition humic-like substances, composted products contain composed complex mixture relatively low molecular weight polymeric materials. The FT-IR and 1H-NMR spectra DOM extracted from clay-loam (SDOM), compost (CDOM), soil-compost mixtures incubated for varying time periods are reported. One samples taken freshly prepared...
The biofortification of food crops for human consumption is a direct strategy increasing dietary intake selenium (Se). aim this study was to evaluate the possibility Se content extra virgin olive oil (EVOO) by spraying tree canopy with sodium selenate and effect increase in on chemical properties sensory characteristics EVOO. treatments were up 50 times more effective enhancing EVOO compared untreated controls. concentration all samples can be considered adequate useful providing diet...
Salt stress and selenium are known to elicitate the production of plant secondary metabolites with antioxidant properties. On this basis, maize grains obtained from mother plants fertilized or not were sprouted at different levels salinity (0, 25, 50 mM NaCl) evaluate effects on sprout yield, inorganic organic Se species, minerals, metabolites, as revealed by a metabolomics analysis. Grain endogenous (135 mg kg−1 vs. 0.19 non-enriched grain) affected yield composition, having greatest effect...
Climate change, currently taking place worldwide and also in the Mediterranean area, is leading to a reduction water availability groundwater salinization. Olive represents one of most efficient tree crops face these scenarios, thanks its natural ability tolerate moderate salinity drought. In present work, four olive cultivars (Koroneiki, Picual, Royal de Cazorla Fadak86) were exposed high salt stress conditions (200 mM NaCl) greenhouse, order evaluate their tolerance level identify key...
Abstract Amendments with pig slurry containing dissolved organic matter (PSDOM) and herbicide coapplication are agronomical practices that can influence the mobility of herbicides through soil profile, thus enhancing risk groundwater pollution. Batch equilibrium experiments were conducted on a clay loam to quantify these sorption desorption three s‐triazine herbicides: atrazine (2‐chloro‐4‐ethylamino‐6‐isopropylamino‐l,3,5‐triazine), prometryn (2,4‐bis...
