Megjegyzések:Water deficit stress is an abiotic stress that causes reductions in growth and yield of many field crops around the world. The present research was aimed to elucidate the mitigating efficiency of exogenous application of select osmoregulators and biostimulants, i.e., potassium dihydrogen phosphate, actosol? (humic acid), Amino more (amino acids), and Compound fertilizer, applied as a spray that reached both foliage and the soil, on growth characteristics, antioxidant capacity, and productivity of barley (Hordeum vulgare L. Giza123) under water deficit stress during two successive growing seasons of field experiments in Egypt. Water deficit resulted in stress as estimated by stress indicators and decreased growth and poor health and development as reflected in statistically significant decreases in chlorophyll a and b and major nutrient (NPK) levels in tissues, stem length, number of leaves, and fresh and dry mass as well as yield components such as spike length, grains per spike, biological yield, grain yield, and 1000-grain weight. As a response to water deficit stress, reactive oxygen species (ROS, i.e., superoxide and hydrogen peroxide) levels increased significantly resulting in lipid peroxidation and decreased membrane integrity and significant increases in antioxidant enzymes such as catalase (CAT), polyphenol oxidase (PPO), and peroxidase (POX). All four treatments alleviated the detrimental impacts of water deficit stress as evidenced by statistically significantly increased photosynthetic pigment concentration, tissue NPK levels, growth, and yield parameters compared to the water deficit-stressed control, while the stress responses were significantly reduced. The osmoregulators used either partially restored the growth and yield of osmotic-stressed barley plants or certain treatments enhanced them. All osmoregulators tested mitigated the adverse impacts of water deficit stress on barley plants, but the highest induction was found when plants were treated with actosol?. The beneficial effects of the osmoregulators tested were the strongest overall in the order actosol(R) > potassium dihydrogen phosphate > Amino more > Compound fertilizer.

Cím:Engineered silica nanoparticles alleviate the detrimental effects of Na+ stress on germination and growth of common bean (Phaseolus vulgaris) / Abdullah H. Alsaeedi, Hassan El-Ramady, Tarek Alshaal, Mohamed El-Garawani, Nevien Elhawat, Mahdi Almohsen

Megjegyzések:During the past 10 years, exploiting engineered nanoparticles in agricultural sector has been rapidly increased. Nanoparticles are used to increase the productivity of different crops particularly under biotic and abiotic stresses. This study aims to test the ability of nanosilica (NS) to ameliorate the detrimental impact of Na+ with different concentrations on the seed germination and the growth of common bean seedlings. Five doses of Na+ have been prepared from NaCl, i.e., 1000, 2000, 3000, 4000, and 5000 mg L-1, and distilled water was applied as a control. Seeds and seedlings were treated with three different NS concentrations (100, 200, and 300 mg L-1). The results proved that Na+ concentrations had detrimental effects on all measured parameters. However, treating seeds and seedlings with NS improved their growth and resulted in higher values for all measurements. For instance, the addition of 300 mg L-1 NS leads to an increase of the final germination percentage,vigor index, and germination speed for seeds irrigated with 5000 mg Na+ L-1 by 19.7, 80.7, and 22.6%, respectively. Although common bean seedlings could not grow at the highest level of Na+, fortification seedlings with NS helped them to grow well under 5000 mg L-1 of Na+. An increase of 11.1 and 23.1% has been measured for shoot and root lengths after treating seedlings with 300 mg L-1 NS under irrigation with 5000 mg Na+ L-1 solutions, and also at the same treatment, shoot and root dry masses are enhanced by 110.9 and 328.0%, respectively. These results proved the importance of using NS to relieve the detrimental effects of Na+-derived salinity. This finding could be reinforced by low Na content which was measured in plant tissues after treating seedlings with 300 mg L-1 of NS.

Cím:Uptake of nicotine from discarded cigarette butts? A so far unconsidered path of contamination of plant-derived commodities / Dirk Selmar, Alzahraa Radwan, Neama Abdalla, Hussein Taha, Carina Wittke, Ahmed El-Henawy, Tarek Alshaal, Megahed Amer, Maik Kleinwachter, Melanie Nowak, Hassan El-Ramady

Megjegyzések:This study aimed to elucidate the origin of the widespread nicotine contamination of plant-derived commodities, by conducting field experiments with various herbs and spice plants. By scattering tobacco and cigarette butts on the field and subsequent nicotine analyses of the acceptor plants, we verified that the alkaloid is leached out into the soil and is taken up by the crop plants. This path of contamination pertains even when there is only one cigarette butt per square meter. Even such minor pollution results - at least in the case of basil and peppermint - in considerable high nicotine contaminations, which exceed the maximum residue level by more than 20-fold. The data reported here clearly outline the large practical relevance of this soil-borne contamination path and imply that unthoughtful disposal of cigarette butts in the field by farm workers may be the reason for the widespread occurrence of nicotine contamination in plant-derived commodities. Therefore, such misbehavior needs to be prevented using education and sensitization, and by including this issue into the guidelines of good agricultural practice.
