“…Under high salinity stress, the application of nano Zn to the soil enhanced crop productivity in Triticale by 39% compared with the control set without nano Zn addition [100]. Significant improvement in fresh weight and dry weight in rice [101], production of biomass in sunflower [102], and crop yield in wheat [92] have been reported under salt stress as a result of the application of nano Zn at the rates of 25 or 50 mgl −1 .…”

Abiotic stress factors are considered a serious threat to various growth parameters of crop plants. Stressors such as drought, salinity, and heavy metals (HMs) hamper the chlorophyll content in plants, resulting in low photosynthesis, hinder the integrity of cell membranes, reduce biomass, and overall growth and development of crops which ultimately results in the sharp decline of crop yield. Under such stressful conditions, various strategies are employed to overcome hazardous effects. Application of Zinc (Zn) or Selenium (Se) in different forms is an effective way to alleviate the abiotic stresses in plants. Zn and Se play a pivotal role in enhancing the chlorophyll level to improve photosynthesis, reducing oxidative stress by limiting reactive oxygen species (ROS) production, controlling HMs absorption by plant roots and their accumulation in the plant body, maintaining homeostasis, and alleviating all the detrimental effects caused by abiotic stress factors. The current review is focused on the usefulness of Zn and Se application, their uptake, sensitization, and different defence mechanisms to relieve adverse effects of abiotic stresses (such as drought, salinity, and HMs) on crops. In this connection, research gaps have also been highlighted.

“…Biochar concentrations increased the antioxidant activities in the wheat plants by improving cell growth, and soil–plant water relationship 67 – 69 . Nanoparticles increased the POD and APX activity to mitigate the water scarcity situation as reported by 70 – 73 . Correlation analysis showed a linear relationship among treatments and recommended the usage of brassinosteroids for increasing stomatal conductance, leaf area index, relative water contents, and chlorophyll contents and for ameliorating the effect of drought stress.…”

Drought stress as a result of rapidly changing climatic conditions has a direct negative impact on crop production especially wheat which is the 2nd staple food crop. To fulfill the nutritional demand under rapidly declining water resources, there is a dire need to adopt a precise, and efficient approach in the form of different amendments. In this regard, the present study investigated the impact of nano-biochar (NBC) and brassinosteroids (BR) in enhancing the growth and productivity of wheat under different drought stress conditions. The field study comprised different combinations of amendments (control, NBC, BR, and NBC + BR) under three irrigation levels (D0, D1 and D2). Among different treatments, the synergistic approach (NBC + BR) resulted in the maximum increase in different growth and yield parameters under normal as well as drought stress conditions. With synergistic approach (NBC + BR), the maximum plant height (71.7 cm), spike length (17.1), number of fertile tillers m–2 (410), no. of spikelets spike–1 (19.1), no. of grains spike–1 (37.9), 1000 grain weight (37 g), grain yield (4079 kg ha–1), biological yield (10,502 kg ha–1), harvest index (43.5). In the case of physiological parameters such as leaf area index, relative water contents, chlorophyll contents, and stomatal conductance were maximally improved with the combined application of NBC and BR. The same treatment caused an increase of 54, 10, and 7% in N, P, and K contents in grains, respectively compared to the control treatment. Similarly, the antioxidant response was enhanced in wheat plants under drought stress with the combined application of NBC and BR. In conclusion, the combined application of NBC and BR caused a significant increase in the growth, physiological and yield attributes of wheat under drought stress.

“…A study conducted with Chrysanthemum balsamita L. reported that Zn treatments decreased the content of proline compared to the control group, and the lowest content of proline was obtained from 1 g L −1 Zn treatments [59]. In a study that was conducted in Triticale, it was reported that the Zn fertilizers increased the content of proline, but this increase was not at a significant level [60]. Behtash [61] reported that only zinc treatments did not have a significant effect on proline content, but the content of proline decreased by 337% at a dose of 10 mg L −1 Zn.…”

Galanthus elwesii Hook. is an important plant species of the Amaryllidaceae family and is used for the medicinal purposes of its valuable bioactive compounds. The present study was conducted to investigate the effects of foliar salicylic acid (SA) and zinc (Zn) treatments on the proline, carotenoid, and chlorophyll content and the anti-oxidant enzyme activity in G. elwesii. The ascorbate peroxidase (APX) enzyme activity, catalase (CAT) enzyme activity, and protein contents were determined with ascorbate oxidation, hydrogen peroxide (H2O2), and Bradford experiments, respectively. The plants were treated with three different concentrations of SA (0.5, 1, and 2 mM) and Zn (40, 80, and 120 mM) and were compared with the control. Fresh leaves were harvested in the study. APX (3.99 ± 0.58 EU/mg protein) and CAT (154.64 ± 4.10 EU/mg protein) were obtained from Zn 80 and 120 mM treatments at the highest level, respectively. The proline, chlorophyll b, and carotenoid content increased 12.4, 1.54, and 3.95-fold, respectively, in 0.5 mM SA treatments, when matched with the control group. It was found that increasing doses of SA and Zn increased the content of malondialdehyde (MDA), but this was not at a significant level. The total chlorophyll content increased 2.27-fold in Zn 120 mM + SA 2 mM treatment and the chlorophyll content increased 2.41-fold in Zn 40 mM + SA 1 mM treatment.
