“…In the agricultural industry, a delivery system is a type of formulation that allows the introduction of agrochemicals (phytohormones, pesticides, biopesticides, fertilizers/bio‐fertilizers) into the plant body (Maluin et al, 2020; Riseh et al, 2022; Campos et al, 2023). By regulating the pace, timing, and location of agrochemical release into the plant, this formulation can improve plant life and protect them from various hurdles (De et al, 2014).…”

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 this scenario, the exogenous application of phytohormones and modulators of their homeostasis can be used to minimize the effects of different abiotic stresses on plants [6]. For example, external application of gibberellic acid (GA 3 ) has demonstrated the ability to alleviate some negative impacts of environmental stresses, resulting in enhanced growth, improved photosynthetic efficiency, increased enzyme activity, altered gene expression, higher nutrient uptake, and greater yields in diverse crops facing challenging conditions.…”

“…In addition, polymeric nanocarriers can promote greater solubility and efficiency of agrochemicals (with the consequent reduction in the application dose), as well as a decrease in toxicity in non-target organisms [23]. The use of these systems for plant growth regulators can make them viable as a management strategy to improve plant tolerance to different types of stress [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Furthermore, nanoparticles themselves have been tested as a seed-priming agent (nanopriming), taking advantage of the unique properties of nanomaterials to enhance the benefits of seed priming [24].…”

Water deficit (WD) promotes great losses in agriculture, and the development of new sustainable technologies to mitigate the effects of this stress on plants is essential. This study aimed to evaluate the morphophysiological and biochemical alterations induced by the priming of tomato seeds with different formulations in plants under field capacity and WD conditions. In the first experiment, the treatments consisted of nanoparticles of alginate/chitosan and chitosan/tripolyphosphate containing gibberellic acid (GA3) in different concentrations (0.5, 5, and 50 µg mL−1 GA3), in addition to control with deionized water. The alginate/chitosan (5 µg mL−1 GA3) provided the greatest gains in plant growth under field capacity. In addition, under WD this treatment reduced damage to photosystem II (−14%), stomatal conductance (−13%), and water loss (−38%) and increased the instantaneous carboxylation efficiency (+24%) and intrinsic water use efficiency (+12%). In the second experiment, the treatments were alginate/chitosan nanoparticles containing GA3 (NPGA3 5 µg mL−1), free GA3 (GA3 5 µg mL−1), nanoparticles without GA3 (NP), deionized water (WATER), and non-primed seeds (CONT). Under WD, GA3 and CONT maintained plant growth and lost water rapidly, reducing stomatal conductance (−87%) and net photosynthesis (−69%). In contrast, NPGA3 decreased leaf area (−44%) and increased root-to-shoot ratio (+39%) when compared to GA3, reducing water loss (−28%). Activation of protective mechanisms (e.g., superoxide dismutase and catalase activities) by WATER, NPGA3, and NP treatments also resulted in lower susceptibility to WD compared to CONT and GA3. The results highlight the positive effect of seed priming on plant response to WD, which was enhanced by the use of nanoencapsulated GA3.

“…In this context, the use of growth regulators has become a promising alternative to enhance plants' resistance to various stresses [12]. They can have applications in agriculture, where they promote increased plant growth and development, enhancing resistance to both abiotic and biotic stress [13], as well as increase the quality of agricultural products. Among the most widely used growth regulators, indole-3-acetic acid (IAA) is a key phytohormone in the regulation of plant growth and development [14,15].…”

Indole-3-acetic acid (IAA) is a key plant hormone that plays crucial roles in plant growth and development. This study investigated the effects of exogenous application of IAA as a growth regulator in onion cultivation (Allium cepa L.). Various IAA concentrations were evaluated to determine their effects on onion growth and chemical parameters. Several agronomic properties and chemical parameters, including total fresh weight, plant height, chlorophyll content, nitrates, total phenols, and antioxidant capacity (DPPH), were analyzed. The results revealed that the exogenous application of different concentrations of IAA had a significant impact on onion growth and quality. Specifically, it was found that certain concentrations of IAA fostered a significant increase in fresh bulb weight and a notable elevation in the levels of phenolic compounds. However, the onion’s response to IAA was concentration dependent. In conclusion, the present study offers evidence that the exogenous application of IAA as a growth regulator can enhance onion growth and quality. These findings hold relevance for the advancement of sustainable agricultural practices and can be directed towards crop enhancement.
