“…Reports revealed that drought stress increased the EL, MDA, and H 2 O 2 by scavenging the activities of various protective chemicals such as osmoprotectant, antioxidants, and secondary metabolites, etc. (Ali et al ., 2019a; Adrees et al ., 2020). EBL might have the ability to reduce MDA by decreasing membrane damage (peroxidation) and maintaining the structure and stability of membrane which could enhance the stress tolerance in plants (Talaat and Shawky, 2012; Zhao et al ., 2017).…”

“…On the other hand, drought stress enhanced the activities of antioxidant enzymes which reflects the inhibition of ROS produced under drought conditions. There was a strong correlation between oxidative stress caused by drought and the activities of antioxidant enzymes (Adrees et al ., 2020). The CAT converts O 2 into H 2 O 2 and SOD transforms into water and oxygen (Rizwan et al ., 2019a).…”

“…The MDA contents were estimated as lipid peroxidation in leaves by following the method of (Heath and Packer, 1968) and modified by Dhindsa et al (1981) and Zhang and Kirkham (1994). The H 2 O 2 were recorded by the procedures described by (Adrees et al ., 2020).…”

“…Furthermore, it is estimated that 70% more wheat grains will be required by 2050 to feed the increasing world population (Ray et al ., 2013). At the same time, wheat productivity is drastically decreasing due to environmental stresses especially drought stress (Rizwan et al ., 2015; Adrees et al ., 2020). As a result, drought stress could be a major issue that has a serious impact on wheat and other crops, particularly in the near future.…”

Drought stress is a major limitation in enhancing agricultural productivity to fulfill the food demand for the world's population. Fertigation of plants with a variety of biochemicals is being used to create drought resistance in wheat; however, the previous work has been limited in addressing these issues in plants at different growth stages.Therefore, a greenhouse study was conducted to ameliorate the drought stress in two wheat varieties (Chakwal-50 and Faisalabad-2008) by foliar application of 24-epibrassinolide (EBL). It was evident that drought stress had a negative effect on the growth, photosynthesis, and yield of wheat plants. EBL significantly enhanced the plant growth both under optimal and drought conditions. EBL improved the plant height, spike length, and the dry weights of roots, shoots, and grains as compared to control. Furthermore, the foliar application of EBL positively enhanced the osmolyte accumulation, increased the amounts of photosynthetic pigments, and improved the gas exchange parameters. The EBL minimized the oxidative stress by reducing electrolyte leakage, malondialdehyde, and hydrogen peroxide contents whereas it enhanced the activities of antioxidant enzymes, such as catalase, superoxide dismutase, and peroxidase under drought stress. The EBL significantly improved the level of stress hormones, such as abscisic acid, indol acetic acid, and cytokinin under drought stress. The growth response of Chakwal-50 was higher than that of Faisalabad-2008 when exposed to EBL under drought stress. Overall, the EBL plays a major role in the enhancement of growth, biomass, yield, and decrease in oxidative damage in wheat under drought conditions, however; field investigations with different doses of EBL are needed before any further recommendation. | INTRODUCTIONFood security is a global issue for the development of sustainable agriculture. In the present scenario, the shortage of freshwater required for agriculture has created serious problems for the production of crops with better nutritional quality in near future (Ali et al., 2019a).

“…The wheat variety Pakistan-2013 is drought tolerant (V1) and NARC-2011 is drought susceptible (V2). The seeds were sterilized by using a 10% of sodium hypochlorite solution for 15 min followed by washing with double-distilled water [25]. The research experiment was carried out from November 2019 to February 2020 within an experimental zone (Glasshouse) at PMAS-Arid Agriculture University Rawalpindi.…”

The present study was aimed to biosynthesize selenium nanoparticles (SeNPs) and assess their foliar applications to improve the growth of wheat plants under controlled irrigation and drought stress. Bud aqueous extract of Allium sativum L. was used as a reducing and stabilizing agent of SeNPs followed by their optical and morphological characterization by using ultraviolet-visible spectroscopy, scanning electron microscopy, Fourier-transform infrared, and energy dispersive X-ray analysis. Various concentrations of SeNPs (10, 20, 30, and 40 mg/L) were applied exogenously to drought-tolerant (V1) and drought-susceptible (V2) wheat varieties at the trifoliate stage. Under the positive control conditions, plants were irrigated with 450 mL of water/pot (100% field capacity); and under water-deficit environment, plants were irrigated with 160 mL of water/pot (35% field capacity). Remarkable increase in plant height, shoot length, shoot fresh weight, shoot dry weight, root length, root fresh weight, root dry weight, leaf area, leaf number, and leaf length has been observed when 30 mg/L concentration of SeNPs was used. However, the plant morphological parameters decreased gradually at higher concentrations (40 mg/L) in both selected wheat varieties. Therefore, 30 mg/L concentration of SeNPs was found most preferable to enhance the growth of selected wheat varieties under normal and water-deficient conditions.
