Foliar-applied α-tocopherol enhances salt-tolerance in Vicia faba L. plants grown under saline conditions

Improving Performance of Glycine max (L.) by α-tocopherol under Deficit Irrigation in Dry Environments

“…However, foliar-applied TOC treatments have shown to increase growth characteristics, particularly shoot fresh and dry weights in soybean plants. These positive results with TOC were similarly observed earlier for some crops such as soybean (Rady et al, 2015),flax (Sadak & Dawood, 2014),onion (Semida et al, 2016), faba beans (Semida et al, 2014 andOrabi &Abdelhamid 2016). The vitamin TOC, as an antioxidant, deactivates photosynthesisderived reactive oxygen species (ROS), and prevents the increase in lipid peroxidation by scavenging lipid peroxyl radicals in thylakoid membranes.…”

“…In this study, the RWC and MSI were increased as EL was decreased under DI stress by the application of TOC, suggesting maintaining the healthy metabolic processes in soybean leaves. Semida et al, (2014) and Rady et al, (2015) concluded that there is a relationship between the RWC and the biomass (fresh and dry weights) in soybean under the interactive effect of DI stress and TOC application. This indicates that the water status of soybean leaves is basically dependent on the respective shoot biomass.…”

“…It has been a positive correlation between each of the shoot/root growth and TOC in two grass species; tall fescue and creeping bentgrass (Zhang and Schmidt, 2000), plant performance and TOC (Semida et al, 2014 andRady et al, 2015), and antioxidant system (enzymatic and non-enzymatic antioxidants) and TOC (Orabi & Abdelhamid, 2016andSemida et al, 2016.…”

Foliar applications of alpha-tocopherol improves the composition of fresh pods of Vigna radiata subjected to water deficiency

“…They further established that α-Toc treatment led to the accumulation of total carbohydrates in sunflower plants (Sadak et al, 2010). A significant reduction in the total soluble sugars due to α-Toc application to Vicia faba plants was observed by Semida et al (2014). The authors suggested that this reduction in soluble sugars may be attributed to the crucial role of α-Toc in mitigating the negative effects of soluble salts.…”

Einfluss der Anwendung einer Aminosäurenmischung auf einige biochemische Aspekte, antioxidative Enzyme und endogene Polyamine der Pflanze Vicia faba bei Stress durch Salz aus Meerwasser

“…Foliar spraying with amino acids mixture with different concentrations could alleviate partially or completely the effect of seawater salinity stress as et al (2013a, b), and Dawood et al (2014a, b) reported an increase in the concentration of proline on faba bean plants under salt stress. Semida et al (2014Semida et al ( , 2015 reported also an increase in leaf and root proline concentration under salinity stress. It is likely that salinity stress generated a physiological drought that leads to an activation of the enzymes of proline biosynthesis and resulted in higher concentration of the proline ( Table 2).…”
