“…No information is available on the foliar application of maize plants with a maize grain extract (MEg) enriched with silymarin (Sm); MEg-Sm to attenuate the adverse impacts of cadmium (Cd) stress on plant performance, which responded positively to the novel MEg-Sm. Recently, some articles have been reported positive changes in plant growth, biochemical attributes, and plant defensive system (e.g., antioxidative enzymes and nonenzymatic antioxidants) after treating plants with MEg alone under some stresses [ 3 , 20 , 21 , 22 , 23 ], indicating the importance of MEg. However, the current study provides impressive results such as a considerable increase in maize plant performance and defense system along with gene expression related to antioxidant enzymes due to the application of MEg-Sm, which outperformed MEg alone due to that Sm increased the efficiency of the extract.…”

“…Often, the endogenous antioxidant defense system is not sufficient for the plant to defend against environmental foes, including Cd. Thus, a plant extract known to be a biostimulant, such as maize grain extract (MEg), can be used as a foliar spray and/or seed priming solution to support plants to increase their tolerance to environmental opponents [ 3 , 20 , 21 , 22 , 23 ], including Cd stress [ 3 ].…”

“…Presently, MEg has been used to enhance plant efficiency under different stress conditions, including Cd stress, as it is an essential organic biostimulator rich in many growth-promoting substances for different stressed plants, such as antioxidants, phytohormones, and essential nutrients [ 3 ]. After applying MEg, plant morphology, physiology, and biochemistry have been positively modified along with stimulation of plant tolerance against damage of some stresses [ 3 , 20 , 21 , 22 , 23 ]. Therefore, MEg is a potent novel biostimulator to give stressed plants the power to resist damage from environmental opponents.…”

For maize, the potential preventive role of foliar spraying with an extract derived from maize grain (MEg, 2%), silymarin (Sm, 0.5 mM), or silymarin-enriched MEg (MEg-Sm) in attenuating the stress effects of cadmium (Cd, 0.5 mM) was examined using a completely randomized design layout. Under normal conditions, foliar spraying with MEg, Sm, or MEg-Sm was beneficial (with MEg-Sm preferred) for maize plants, whereas the benefit was more pronounced under Cd stress. The use of Cd through irrigation water decreased plant growth traits, photosynthetic efficiency, including instantaneous carboxylation efficiency, Fv/Fm, and pigment contents, and hormonal contents (e.g., auxin, gibberellins, cytokinins including trans-zeatin, and salicylic acid). These undesired findings were due to an increase in Cd content, leading to increased levels of oxidative stress (O2•− and H2O2), ionic leakage, and lipid peroxidation. Therefore, this damage resulted in an increase in the activities of nonenzymatic antioxidants, Sm, antioxidative enzymes, and enzyme gene expression. However, under Cd stress, although foliar spray with MEg or Sm had better findings than control, MEg-Sm had better findings than MEg or Sm. Application of MEg-Sm greatly increased photosynthesis efficiency, restored hormonal homeostasis, and further increased the activities of various antioxidants, Sm, antioxidative enzymes, and enzyme gene expression. These desired findings were due to the suppression of the Cd content, and thus the levels of O2•−, H2O2, ionic leakage, and lipid peroxidation, which were positively reflected in the growth and accumulation of dry matter in maize plants. The data obtained in this study recommend applying silymarin-enriched maize grain extract (MEg-Sm at 0.24 g Sm L−1 of MEg) as a spray solution to maize plants when exposed to excess Cd in soil or irrigation water.

“…Due to the storage of salt in the soil through tidal flow, agricultural land can become unproductive. High NaCl concentrations in irrigation water or soil cause serious economic losses from dry lands [19,20], because salinity stress reduces the growth and productivity of many crop species [21][22][23][24][25]. Several physiological and biochemical processes let plants cope with excessive salt concentrations in saline soils.…”

Two pot experiments were conducted in a greenhouse to examine 14C fixation and its distribution in biochemical leaf components, as well as the physiological and anatomical adaptability responses of wheat (Triticum aestivum L.) grown with seawater diluted to 0.2, 3.0, 6.0, and 12.0 dS m−1. The results showed significant reductions in chlorophyll content, 14C fixation (photosynthesis), plant height, main stem diameter, total leaf area per plant, and total dry weight at 3.0, 6.0, and 12.0 dS m−1 seawater salt stress. The 14C loss was very high at 12.0 ds m−1 after 120 h. 14C in lipids (ether extract) showed significant changes at 12.0 dS m−1 at 96 and 120 h. The findings indicated the leaf and stem anatomical feature change of wheat plants resulting from adaptation to salinity stress. A reduction in the anatomical traits of stem and leaf diameter, wall thickness, diameter of the hollow pith cavity, total number of vascular bundles, number of large and small vascular bundles, bundle length and width, thickness of phloem tissue, and diameter of the metaxylem vessel of wheat plants was found. In conclusion, salt stress induces both anatomical and physiological changes in the stem and leaf cells of wheat, as well as the tissues and organs, and these changes in turn make it possible for the plants to adapt successfully to a saline environment.

“…In this context, it is strategic to adopt some new methods to increase tomato production and improve the growth in an increasing temperatures scenario [ 11 ]. In several harsh environmental conditions such as drought, salt stress, and high temperature, plants endogenous antioxidant networks are not sufficient to protect [ 12 ]. Eventually, several reports have highlighted that cultural practices (e.g., appropriate nutrient solution concentration or use of exogenous adjuvants such as plant extracts) might improve the antioxidant composition of fruits or increase plants tolerance to stress due to different factors including salinity, high temperature, and diseases [ 13 , 14 ].…”

Salicylic acid (SA) and propolis (PR) are known to regulate the physiological process and to have a relevant role in bioactive compounds content. Our experiment was designed to evaluate the effect of SA and PR application on the growth, yield, and quality parameters of tomato grown for the fresh market in field conditions in Egypt. We studied the effect of twelve treatments where SA (0.50, 1.00, 1.50, 2.00, and 2.50 mM) and PR (1, 2, 10, 20, and 100 mg propolis mL−1) were applied at increasing doses as a sole agent or combined each other (1.50 mM + 10 mg mL−1 for SA and PR, respectively). An untreated control was also considered. Tomato plants treated with SA (0.50, 1.00, and 1.50 mM) showed a significant effect in all traits especially SA1 (0.50 mM) in growth parameters and SA2 (1.00 mM) in pigment and antioxidant content. Propolis foliar application was more effective than SA as it revealed that raising the concentration of aqueous extract enhanced the growth parameters and pigment in tomato. The best result was obtained by the 10 mg mL−1 treatment. The effect of propolis on antioxidant enzymes varied as the 10 mg mL−1 treatment was effective on peroxidases and superoxide dismutase, while 100 mg mL−1 was more effective on catalase. Salicylic acid and propolis have a positive effect on both preserving tomato plants and on nutrient supply, so the mixed intermediate concentration (1.50 mM + 10 mg mL−1) is considered very effective and results in an improvement of all plant traits.
