Interactive impacts of microplastics and arsenic on agricultural soil and plant traits.

The ability of microplastics (MPs) to interact with environmental pollutants is currently of great concern due to the increasing use of plastic. Agricultural soils are sinks for multipollutants and the safety of biodegradable MPs in field conditions is questioned. However, still few studies have investigated the interactive effects between MPs and metals on the soil-plant system with agricultural soil and testing crops for human consumption.

Selenium Biofortification Impacts the Tomato Fruit Metabolome and Transcriptional Profile at Ripening.

In the present work, the effects of enriching tomatoes with selenium were studied in terms of physiological, metabolic, and molecular processes in the last stages of fruit development, particularly during ripening. A selenium concentration of 10 mg L with sodium selenate and selenium nanoparticles was used in the spray treatments on the whole plants. No significant effects of selenium enrichment were detected in terms of ethylene production or color changes in the ripening fruit.

Iodine biofortification of Swiss chard (Beta vulgaris ssp. vulgaris var. cicla) and its wild ancestor sea beet (Beta vulgaris ssp. maritima) grown hydroponically as baby leaves: effects on leaf production and quality.

Background: About 35-45% of the global population is affected by iodine deficiency. Iodine intake can be increased through the consumption of biofortified vegetables. Given the increasing interest in wild edible species of new leafy vegetables due to their high nutritional content, this study aimed to evaluate the suitability of Swiss chard (Beta vulgaris ssp.

A Preliminary Study on Lupinus albus and Raphanus sativus Grown in Soil Affected by Oil Spillage.

Oil spills from pipelines are a hazardous contamination source for agricultural soils. We investigated the effects of petroleum hydrocarbon (PHC) soil contamination, resulting from a real diesel oil pipeline spill, on the growth of Lupinus albus and Raphanus sativus plants. These species are widely cultivated for food purposes and have not been previously tested in soils affected by oil spills.

Se-Enrichment Pattern, Composition, and Aroma Profile of Ripe Tomatoes after Sodium Selenate Foliar Spraying Performed at Different Plant Developmental Stages.

Foliar spray with selenium salts can be used to fortify tomatoes, but the results vary in relation to the Se concentration and the plant developmental stage. The effects of foliar spraying with sodium selenate at concentrations of 0, 1, and 1.5 mg Se L at flowering and fruit immature green stage on Se accumulation and quality traits of tomatoes at ripening were investigated.

Selenium Enrichment Enhances the Quality and Shelf Life of Basil Leaves.

The biofortification of leafy vegetables with selenium (Se) is a good way to increase human dietary Se intake. In addition, selenium delays plant senescence by enhancing the antioxidant capacity of plant tissues, decreasing postharvest losses. We investigated the effects of selenium addition on the production and quality of sweet basil () leaves of two harvesting phases, hereafter referred to as cuts, during the crop cycle.

Production of selenium-biofortified microgreens from selenium-enriched seeds of basil.

Background: Microgreens (i.e. tender immature greens) are a popular alternative to sprouts (i.

Effect of selenium enrichment on metabolism of tomato (Solanum lycopersicum) fruit during postharvest ripening.

Background: Selenium (Se) enrichment of plants seems effective in enhancing the health-related properties of produce and in delaying plant senescence and fruit ripening. The current study investigated the effects of Se on tomato fruit ripening. Tomato (Solanum lycopersicum L.

Selenium Enrichment of Horticultural Crops.

The ability of some crops to accumulate selenium (Se) is crucial for human nutrition and health. Selenium has been identified as a cofactor of the enzyme glutathione peroxidase, which is a catalyzer in the reduction of peroxides that can damage cells and tissues, and can act as an antioxidant. Plants are the first link in the food chain, which ends with humans.

Effects of phosphate and thiosulphate on arsenic accumulation in the species Brassica juncea.

Arsenic (As) is recognized as a toxic pollutant in soils of many countries. Since phosphorus (P) and sulphur (S) can influence arsenic mobility and bioavailability, as well as the plant tolerance to As, phytoremediation techniques employed to clean-up As-contaminated areas should consider the interaction between As and these two nutrients. In this study, the bioavailability and accumulation of arsenate in the species Brassica juncea were compared between soil system and hydroponics in relation to P and S concentration of the growth substrate.

Effects of foliar and fruit addition of sodium selenate on selenium accumulation and fruit quality.

Background: We investigated the effects of the foliar and fruit application of sodium selenate on selenium (Se) accumulation, fruit growth and ripening in peach and pear. Trials were conducted in two growing seasons. In 2008 selenate was applied at a rate of 0.

Assessment of the agronomic and technological characteristics of Triticum turgidum ssp. dicoccum Schrank and T. spelta L.

Recently, the peoples interest in natural and organic products led to a "rediscovery" of hulled wheat, particularly T. turgidum ssp. dicoccum, commonly known as "farro".
