| Abstract | ||||
| Salinity is a major abiotic stressor that affects plant cell metabolism and reduces plant yield. Numerous beneficial effects on plants' ability to withstand abiotic stressors have been linked to biostimulants like ascorbic acid (AsA). But not much is known about AsA's effects on important medical compounds (caffeic acid, syringic acid, rosmarinic acid, ellagic acid, ferulic acid, methyl gallate, vanillin, naringenin, rutin, daidzein, and quercetin) of barley grains produced under different doses of salinity. So, in our study we showed the effect of different salinity levels (4000 and 8000 ppm of sodium chloride) in the presence or absence AsA (at 100 and 200 ppm) on phenolic profile in grains of barley plant by high-performance liquid chromatography analysis. Pigments, carbohydrates, protein, proline, phenolic and flavonoid compounds of barley shoot (Hordeum vulgare L. (Giza 134) also investigated. AsA at 100 ppm appeared the highest values of caffeic acid, syringic acid, rosmarinic acid, ellagic acid, ferulic acid, methyl gallate, vanillin, naringenin, rutin, daidzein, and quercetin under 4000 ppm of salt compared with control and other treatments, AsA showed significant improvement in contents of pigments, carbohydrates, protein, proline, phenolic, and flavonoids compounds of barley shoot under salinity stress. By employing environmentally safe natural products, the search aims to enhance the metabolites of barley plants, particularly phenolic compounds. This might lead to an improvement in the caliber of significant crops grown in salinized environments. We also have shown that the harmful effects of salt stress on the metabolites of Hordeum vulgare plants can be lessened by the exogenous application of AsA. In addition to improving the physiological characteristics of barley shoots, this treatment lowers oxidative stress in plants by increasing phenolic chemicals. | ||||
