“…Zaghloul at the stages of cell division and cell elongation significantly improved the fruit content from dry matter, ash, soluble solids, and a reduction in non-reducing and total soluble sugars, as well as carbohydrate, protein, amino acid, N, P, K, Ca, Mg, Zn, Fe, and Mn content. In addition, the levels of phytohormones such as indole-3-acetic acid, cytokinins, GA 3 , and SA were also greatly improved, but the applied treatment, on the other hand, minimized the fruit content from the percentages of moisture, total acidity, total phenols, and tannins [42].…”

Ensuring the sustainability of horticultural production is crucial to meeting consumer demand, and the most effective approach involves enhancing the efficient utilization of resources to support the production of wholesome foods. Plant biostimulants are substances defined by their ability, when applied to plants or the rhizosphere, to enhance root development, resulting in heightened vigor. They facilitate the more effective uptake and translocation of nutrients and water throughout the growing season. Additionally, these biostimulants contribute to improved plant health and quality by supplying essential nutrients that stimulate overall growth and metabolic processes. Therefore, this study was performed to examine the impact of some biostimulants on the possibility of improving vegetative growth, yield, fruit quality, and the leaf mineral content of mango cv. Keitt. Mango trees were sprayed with Putrescine at 25, 50, and 100 mg/L; Brassinosteroids at 0.5, 1, and 2 mg/L; and Chitosan at 500, 1000, and 1500 mg/L four times starting from mid-April, with three-week intervals during the seasons of 2021 and 2022. The results showed that the foliar application of these three biostimulants improved the growth, yield, and fruit quality of mango trees as opposed to untreated trees during two study seasons. The results also showed that the foliar application of 1500 mg/L of Chit, 2 mg/L of Brs, and 100 mg/L of Put gave the highest increments for inducing the number, length, and thickness of shoots, leaf area, and leaf chlorophyll over the other applied treatments. In addition, it also heightened the fruit set, fruit yield, and the fruit’s physical and chemical characteristics in both experimental seasons.

“…Foliar application of KNO 3 has been reported to improve mango fruit productivity by stimulating flower induction and inhibiting fruit growth, by increasing cell elongation and cell division [56,57]. Moreover, foliar spray of putrescine has been reported to display favorable changes on fruit growth, in addition to some physical and chemical characteristic changes [58,59]. In addition, fruit set, retention, and quality, and yield of trees grown could be improved by spraying putrescine [37].…”

The current investigation represents of the synergistic effects of application of potassium nitrate (KNO3) in combination with putrescine (Put) on flowering, productivity, and fruit quality on Ewais mango (Mangifera indica L.) trees during the seasons 2021/2022 and 2022/2023. The selected trees were sprayed at three different stages, including flower bud differentiation, full bloom, and beginning of the fruit set, with one of the following treatments: control, 2% KNO3, 4% KNO3, 50 ppm Put, 75 ppm Put, 2% KNO3 + 50 ppm Put, 2% KNO3 + 75 ppm Put, 4% KNO3 + 50 ppm Put, 4% KNO3 + 75 ppm Put. Results showed that all treatments were successful in improving the productivity of mango trees by increasing flowering terminal shoots, fruit set, fruit retention, number of fruits/tree, yield, and fruit yield increment while reducing the percentage of fruit drop, as well as improving the quality of mango fruits cv. Ewais by increasing fruit length, fruit diameter, TSS, total sugars, V.C, and total phenol and carotenoid content, but at the same time, diminishing the total acidity, as compared with control. Based on this research, the application of 4% KNO3 in conjunction with 75 ppm Putrescine has shown the most prominent advances in enhancing Ewais tree productivity and fruit quality. The investigation successfully highlighted the synergistic effect of using KNO3 and putrescine to improve mango fruit yield and quality.

The production of crops is severely limited by water scarcity. We still do not fully understand the underlying mechanism of exogenous melatonin (MT)-mediated water stress tolerance in barley. This study is the first of its kind to show how MT can potentially mitigate changes in barley’s physio-biochemical parameters caused by water deficiency. Barley was grown under three irrigation levels (100%, 70%, and 30% of field capacity) and was foliar sprayed with 70 μM MT. The results showed that exogenously applied MT protected the photosynthetic apparatus by improving photosynthetic pigment content, photochemical reactions of photosynthesis, Calvin cycle enzyme activity, gas exchange capacity, chlorophyll fluorescence system, and membrane stability index. Furthermore, the increased levels of salicylic acid, gibberellins, cytokinins, melatonin, and indole-3-acetic acid, as well as a decrease in abscisic acid, indicated that foliar-applied MT greatly improved barley water stress tolerance. Additionally, by increasing the activity of antioxidant enzymes such as superoxide dismutase, catalase, ascorbate peroxidase, monodehydroascorbate reductase, dehydroascorbate reductase, and glutathione reductase and decreasing hydrogen peroxide content, lipid peroxidation, and electrolyte leakage, MT application lessened water stress-induced oxidative stress. According to the newly discovered data, MT application improves barley water stress tolerance by reprogramming endogenous plant hormone production and antioxidant activity, which enhances membrane stability and photosynthesis. This study unraveled MT’s crucial role in water deficiency mitigation, which can thus be applied to water stress management.
