Abstract Background Salinity is a major threat to rice growth and productivity. Utilizing wild rice-derived genes biostimulants with high promoting- stress-alleviating potential can significantly improve salinity tolerance in cultivated rice. Herein, we investigated the vegetative physiological responses of Giza 177 ( Oryza sativa , sensitive, high-yielding cultivar) promising introgression salt tolerant line sativa/glaberrima ; SG 65) from population × African glaberrima ) under low (2.75...
Through interactions with plant cells, silver nanoparticles (AgNPs) both biological and chemical origins can stimulate physiological metabolic processes in plants. To ensure their safe application the food chain, it is necessary to investigate effects on systems. Therefore, of AgNPs (chem-AgNPs) biologically synthesized (bio-AgNPs) at different levels (i.e., 0, 10, 50 ppm) biochemical traits {i.e., root shoot growth traits, photosynthetic pigments (Chl a, Chl b, carotenoids, total pigments),...
The impacts of varied concentrations copper (Cu) or cadmium (Cd) on the oxidative stress experienced by shoots and roots Phaseolus vulgaris plants were examined in this study. Hydrogen peroxide (H2O2), lipid peroxidation, electrolyte leakage, as well ascorbate (AsA), reduced glutathione (GSH) total phenolic contents significantly increased all heavy metals used, except for 10− 6 M concentration Cu which appeared to induce an insignificant increase above control value. On other hand,...
THIS STUDY evaluated the impact of cobalt (Co) nutrition at optimum concentration on growth and oxidative stress in two Egyptian rice varieties (Sakha 104 Giza 178) under drought stress. The was applied different irrigation intervals (six eight days), after four days set as control through reproductive stage. roots shoots parameters (lengths, fresh dry weights), biomarkers; membrane injury, lipid peroxidation, proline accumulation, protein content, total phenols, flavonoids contents, along...
Element content, growth and metabolic changes in Cu-and Cdstressed Phaseolus vulgaris plantsA large-scale pot experiment was accomplished for investigation of the varied effects different concentrations Cu Cd on certain attributes roots shoots plants, over a period three weeks.Plants supplemented with at 10 -6 -3 M, showed increased levels both roots, above those controls.However, or accumulation lower than roots.As compared control levels, low (10 M) concentration induced either significant...
Addition of a recommended dose phosphorein biofertilizer into salinized soil, induced significant increases in all growth and reproductive parameters determined growing lettuce plants throughout the entire period experiment. On other hand, fertigation such sodic salty soil with nitrobein biofertilizer, slight, if any decreases, at vegetative, flowering fruiting stages. The contents carbohydrates fractions as well pigment activity PS II, fertigated were increased three successive stages,...
T HE PRESENT study is aimed at investigating the drought stress responses of two Egyptian rice varieties (Sakha 104 and Giza 178) after grain soaking in cobalt nutrient solution optimum concentration before sowing soil gaining physiological insights into tolerance plants.The was applied according to different irrigation intervals (control; every 4 days, moderate; 6 days; severe; 8 days).The results showed variable reductions tiller number/plant, barring panicles/plant, panicle length/plant,...
Interactive effects of (proline, ascorbic acid, reduced glutathione and salicylic acid) either alone or in combination with 50 300 mM NaCl on seedling growth, lipid peroxidation electrolyte leakage two phenotypes {salt-sensitive (cv.Giza 716) salt-tolerant 843)} broad bean after priming were investigated.Treatment the germinating seeds both cultivars induced progressive significant decrease fresh mass, dry water content, relative growth index (RGI), rate (RGR), length radicle plumule but...
