“…These DHS components can help plants to withstand and recover from environmental stressors [17,24,25,65]. Furthermore, these findings align with prior studies indicating that using soluble sugars as BSs has a central regulatory function in steering plant growth, and can significantly enhance crop growth and yield while also impacting the capacity of plants to cope with environmental stress factors [25,[66][67][68][69][70][71][72][73][74]. The same central roles are well-proven for antioxidants, including proline, and the nutrients have been demonstrated as effective mechanisms in elevating the ability of plants to withstand environmental stressors [25,26,65].…”

Excessive use of nitrogen (N) pollutes the environment and causes greenhouse gas emissions; however, the application of eco-friendly plant biostimulators (BSs) can overcome these issues. Therefore, this paper aimed to explore the role of diluted bee honey solution (DHS) in attenuating the adverse impacts of N toxicity on Phaseolus vulgaris growth, yield quality, physio-chemical properties, and defense systems. For this purpose, the soil was fertilized with 100, 125, and 150% of the recommended N dose (RND), and the plants were sprayed with 1.5% DHS. Trials were arranged in a two-factor split-plot design (N levels occupied main plots × DH– occupied subplots). Excess N (150% RND) caused a significant decline in plant growth, yield quality, photosynthesis, and antioxidants, while significantly increasing oxidants and oxidative damage [hydrogen peroxide (H2O2), superoxide (O2•−), nitrate, electrolyte leakage (EL), and malondialdehyde (MDA) levels]. However, DHS significantly improved antioxidant activities (glutathione and nitrate reductases, catalase, ascorbate peroxidase, superoxide dismutase, proline, ascorbate, α-tocopherol, and glutathione) and osmoregulatory levels (soluble protein, glycine betaine, and soluble sugars). Enzyme gene expressions showed the same trend as enzyme activities. Additionally, H2O2, O2•−, EL, MDA, and nitrate levels were significantly declined, reflecting enhanced growth, yield, fruit quality, and photosynthetic efficiency. The results demonstrate that DHS can be used as an eco-friendly approach to overcome the harmful impacts of N toxicity on P. vulgaris plants.

“…The major vital components of the BHS have previously been used individually as foliar applications with success supporting plant performance and increasing its resistance to stress, e.g., organic acids [ 63 ], soluble sugars [ 64 , 65 ], amino acids [ 66 , 67 , 68 ], proline [ 66 , 69 ], essential nutrients [ 70 , 71 , 72 ], ascorbate [ 73 ], B-group vitamins [ 74 , 75 ], selenium [ 7 ], and iodine [ 76 ]. In this paper, all of these components are combined into a solution (BHS) in organic forms, giving this solution a multi-mechanism for plants to adjust to stress conditions and resist stress via signaling pathways and efficient mechanisms.…”

Bee-honey solution (BHS) is considered a plant growth multi-biostimulator because it is rich in osmoprotectants, antioxidants, vitamins, and mineral nutrients that can promote drought stress (DtS) resistance in common bean plants. As a novel strategy, BHS has been used in a few studies, which shows that the application of BHS can overcome the stress effects on plant productivity and can contribute significantly to bridging the gap between agricultural production and the steady increase in population under climate changes. Under sufficient watering (SW (100% of crop evapotranspiration; ETc) and DtS (60% of ETc)), the enhancing impacts of foliar application with BHS (0%, 0.5%, 1.0%, and 1.5%) on growth, productivity, yield quality, physiological-biochemical indices, antioxidative defense ingredients, and nutrient status were examined in common bean plants (cultivar Bronco). DtS considerably decreased growth and yield traits, green pod quality, and water use efficiency (WUE); however, application of BHS at all concentrations significantly increased all of these parameters under normal or DtS conditions. Membrane stability index, relative water content, nutrient contents, SPAD (chlorophyll content), and PSII efficiency (Fv/Fm, photochemical activity, and performance index) were markedly reduced under DtS; however, they increased significantly under normal or DtS conditions by foliar spraying of BHS at all concentrations. The negative impacts of DtS were due to increased oxidants [hydrogen peroxide (H2O2) and superoxide (O2•−)], electrolyte leakage (EL), and malondialdehyde (MDA). As a result, the activity of the antioxidant system (ascorbate peroxidase, glutathione reductase, catalase, superoxide dismutase, α-tocopherol, glutathione, and ascorbate) and levels of osmoprotectants (soluble protein, soluble sugars, glycine betaine, and proline) were increased. However, all BHS concentrations further increased osmoprotectant and antioxidant capacity, along with decreased MDA and EL under DtS. What is interesting in this study was that a BHS concentration of 1.0% gave the best results under SW, while a BHS concentration of 1.5% gave the best results under DtS. Therefore, a BHS concentration of 1.5% could be a viable strategy to mitigate the DtS impairment in common beans to achieve satisfactory growth, productivity, and green pod quality under DtS.

“…In addition to these effects, studies have showed that pre-soaked with Glc promotes seed germination and growth in Indian mustard under salinity (Sami et al, 2021). Exogenously sourced Glc alleviates drought stress in wheat (Zahid et al, 2018), induced the bioactive compounds contents in almost all combined treatments (priming seeds and spray) in radish sprouts (Baenas et al, 2019) and enhanced root density, primary root length, and lateral root number in tomato seedlings (González-Hernández et al 2020).…”

Glucose promotes increases in physiological processes related to plant growth and induces cell division and can also act in seed germination. The present investigation has been carried out on the influence of various concentrations of glucose on the germination performance of soybeans seeds of cv. BMX and 66i68. Seeds of soybeans (Glycine max (L.) Merrill) were treated with three concentrations of the glucose (0.05, 0.10 and 0.20 mmol L-1), and a control with distilled water. Tests of seed germination and vigor were carried out: it was calculated the germination percentage (first and final counting), percentage of normal seedlings; and speed of germination, length of the primary root and the aerial part of seedlings were recorded. The experiment was arranged in a completely randomized design with three treatments and five repetitions depending on the test. Increasing doses of the plant growth regulator influence the germination and can increase the speed of germination. The use of glucose in the treatment of soybean seeds, increases the rate of germination and emergence speed, growth of the root system and medium of seedlings. Soybean cultivar BMX seeds showed an increase in physiological performance with increasing glucose dosage.
