“…Abscisic acid, ethylene, auxin, gibberellic acid, cytokinin, jasmonic acid, salicylic acid, brassinosteroids, and polyamines are phytohormones involved in the defence responses to abiotic stimuli (Morkunas et al, 2014;Sharma et al, 2023). The crucial roles of abscisic acid (ABA), ethylene (ET), indole acetic acid (IAA), cytokinin (CK), jasmonic acid (JA), salicylic acid (SA) in plant signalling pathways have been strongly demonstrated by different studies, although the protective mechanisms generated by some phytohormones [such as gibberallic acid (GA), brassinosteroids (BRs), and polyamines (Pas)] have received less attention (Zhao et al, 2021;Rahman et al, 2023;Sharma et al, 2023).…”

Climate change is increasing the stresses on crops, resulting in reduced productivity and further augmenting global food security issues. The dynamic climatic conditions are a severe threat to the sustainability of the ecosystems. The role of technology in enhancing agricultural produce with the minimum environmental impact is hence crucial. Active molecule/Plant growth regulators (PGRs) are molecules helping plants' growth, development, and tolerance to abiotic and biotic stresses. However, their degradation, leaching in surrounding soil and ground water, as well as the assessment of the correct dose of application etc., are some of the technical disadvantages faced. They can be resolved by encapsulation/loading of PGRs on polymer matrices. Micro/nanoencapsulation is a revolutionary tool to deliver bioactive compounds in an economically affordable and environmentally friendly way. Carrier‐based smart delivery systems could be a better alternative to PGRs application in the agriculture field than conventional methods (e.g., spraying). The physiochemical properties and release kinetics of PGRs from the encapsulating system are being explored. Therefore, the present review emphasizes the current status of PGRs encapsulation approach and their potential benefits to plants. This review also addressed the mechanistic action of carrier‐based delivery systems for release, which may aid in developing smart delivery systems with specific tailored properties in future research.

“…In addition, it can act separately or coordinate with other signaling pathways in a complex network. Cross-talk between the different hormones results in synergetic or antagonistic interactions that play crucial roles in the response of plants to abiotic stress [23,24]. Currently, the application of synthetic auxins or ethylene inhibitors as plant growth regulators are successfully practiced and mainly used in various countries, including all aspects of modern apple production to control and manipulate vegetative growth and regulation of flowering, reduce immature fruit drop, pre-harvest drops, fruit maturity, firmness, and manage apple harvest; they can also improve fruit quality and development while reducing ripening, which help improve the post-harvest life and final quality of fruit for better marketability [25][26][27][28][29][30][31][32][33].…”

In order to improve the resistance of apples to stresses (abiotic stresses) during hot and dry summers to enhance their productivity and marketability, Anna apple trees were treated with aminoethoxyvinylglycine (AVG), 1-methlcyclopropene (1-MCP), and naphthalene acetic acid (NAA), alone, or in combination, in two successive seasons. All treatments significantly increased the yield per tree, the average fruit volume, fruit diameter, and fruit weight compared to the control (growing under hot and dry summers without any treatments). All treatments significantly reduced the apple size, total soluble solid (TSS) content, anthocyanin content, carotenoid content, total sugar solids, and sugar percentage, and they led to fruit softening, loss of fruit weight, firmness, breakdown percentage, as well as a decreased polyphenol oxidase and peroxidase activity at one-week post-harvest (except for 20-ppm NAA) in comparison with the control. Trees treated with 320-ppm 1-MCP + 250-ppm AVG exhibited maximum yield per tree, fruit firmness, and no-reducing sugars or starch. On the other hand, the 20-ppm NAA produced the maximum TSS content, total sugars, with a reduced sugar percentage, carotenoid and anthocyanin fruit content, and (TSS)/acidity ratio. The application of 320-ppm 1-MCP + 250-ppm AVG effectively delayed the harvest for 14 days compared to the control. Our results show that the sprays of NAA and inhibitors of ethylene had a significant effect on the productivity and marketability of Anna apples under abiotic stresses.

In order to improve Anna apples resistance to hot and dry summer stresses (abiotic stresses) to enhancement the productivity and marketability, Anna apple trees were treated with three growth regulators [naphthalene acetic acid (NAA), 1-methlcyclopropen (1-MCP), and aminoethoxyvinylglycine (AVG)] alone or in combination in two successive seasons. All treatments significantly increased the yield per tree, average fruit volume, fruit diameter and fruit weight compared to control (growing under hot and dry summers which received no treatment). All treatments significantly reduced apple, total soluble solid (TSS) content, fruit softening, anthocyanin content, carotenoid content, total sugar solids, and sugar percentage compared to control. Trees treated with 320-ppm 1-MCP + 250-ppm AVG exhibited maximum yield per tree, fruit firmness, and no-reducing sugars and starch. While 20-ppm NAA produced the maximum TSS content, total sugars, and reducing sugar percentage, carotenoid and anthocyanin fruit content, and (TSS)/acidity ratio. In terms of fruit marketability, the application of all growth regulators remarkably declines the fruit weight loss, fruit firmness loss, and breakdown percentage, as well as decreasing polyphenol oxidase and peroxidase activity at 1-week post-harvest, except for 20-ppm NAA. Additionally, the application of 320-ppm 1-MCP + 250-ppm AVG effectively delayed the harvest for 14 days, whereas the application of NAA effectively moved the harvest date 2 days forward with respect to control. Our results show that specific growth regulator sprays have a significant effect on the productivity and marketability of Anna apples under abiotic stresses
