Abstract

In conventional agricultural practices, pesticides are applied to protect crops from harmful insect pests; however, pervasive usage in high-yield crop systems poses a significant risk to the viability and sustainability of agroecosystems. Agricultural output may be adversely affected by pesticide deposition in the soil as it affects biochemical interactions between plants and soil. Pesticides cause oxidative stress by blocking physiological and biochemical pathways and disrupting the photosynthetic machinery of plants. When exposed to abiotic challenges, plant growth regulators (PGRs) such as auxin, gibberellins, cytokinin and abscisic acid (ABA), salicylic acid (SA), jasmonic acid (JA), brassinosteroids (BR), and 24-epibrassinolides (EBL) reduce pesticide toxicity by strengthening antioxidant defence mechanisms and enhancing tolerance to stressful conditions. By modulating a variety of physio-biochemical mechanisms, PGRs reduce pesticide toxicity in intact plants. Furthermore, PGRs eliminate reactive oxygen species (ROS) generation by inducing antioxidant enzyme production. Pesticide residues in plant compartments are reduced as a result of PGR-mediated increase in pesticide degradation. This review provides a detailed account of the potential role of PGRs in pesticide detoxification and growth promotion in plants. This work examines several elements of plant pesticidal reactions and assesses how PGRs support plants in tolerating pesticides. The underlying mechanisms during pesticide stress are also discussed. The need for additional study on PGR applications is also emphasized.

植物激素与农药之间的相互影响：揭示植物生长调节剂在提高作物抵御农药胁迫能力方面的关键作用

在传统农业实践中，施用杀虫剂是为了保护作物免受有害害虫的侵害；然而，在高产作物系统中普遍使用杀虫剂对农业生态系统的生存能力和可持续性构成了重大风险。农药在土壤中的沉积可能会对农业产出产生不利影响，因为它会影响植物与土壤之间的生化相互作用。农药会阻断植物的生理和生化途径，破坏植物的光合作用机制，从而导致氧化应激。当植物面临非生物挑战时，植物生长调节剂（PGRs），如辅助素、赤霉素、细胞分裂素和脱落酸（ABA）、水杨酸（SA）、茉莉酸（JA）、黄铜类固醇（BR）和 24-表黄酮醇内酯（EBL），可通过加强抗氧化防御机制和提高对胁迫条件的耐受性来降低农药毒性。通过调节各种生理生化机制，植物生长调节剂可降低农药对完整植物的毒性。此外，PGRs 还能通过诱导抗氧化酶的产生来消除活性氧（ROS）的生成。由于 PGR 介导的农药降解增加，植物体内的农药残留也随之减少。本综述详细介绍了 PGRs 在植物农药解毒和促进生长方面的潜在作用。这项工作研究了植物杀虫剂反应的几个要素，并评估了 PGRs 如何支持植物耐受杀虫剂。此外，还讨论了农药胁迫过程中的潜在机制。此外，还强调了对 PGR 应用进行更多研究的必要性。

期刊介绍： Scientia Horticulturae is an international journal publishing research related to horticultural crops. Articles in the journal deal with open or protected production of vegetables, fruits, edible fungi and ornamentals under temperate, subtropical and tropical conditions. Papers in related areas (biochemistry, micropropagation, soil science, plant breeding, plant physiology, phytopathology, etc.) are considered, if they contain information of direct significance to horticulture. Papers on the technical aspects of horticulture (engineering, crop processing, storage, transport etc.) are accepted for publication only if they relate directly to the living product. In the case of plantation crops, those yielding a product that may be used fresh (e.g. tropical vegetables, citrus, bananas, and other fruits) will be considered, while those papers describing the processing of the product (e.g. rubber, tobacco, and quinine) will not. The scope of the journal includes all horticultural crops but does not include speciality crops such as, medicinal crops or forestry crops, such as bamboo. Basic molecular studies without any direct application in horticulture will not be considered for this journal.
