Climate change due to different human activities is causing adverse environmental conditions and uncontrolled extreme weather events. These harsh conditions are directly affecting the crop areas, and consequently, their yield (both in quantity and quality) is often impaired. It is essential to seek new advanced technologies to allow plants to tolerate environmental stresses and maintain their normal growth and development. Treatments performed with exogenous phytohormones stand out because they mitigate the negative effects of stress and promote the growth rate of plants. However, the technical limitations in field application, the putative side effects, and the difficulty in determining the correct dose, limit their widespread use. Nanoencapsulated systems have attracted attention because they allow a controlled delivery of active compounds and for their protection with eco-friendly shell biomaterials. Encapsulation is in continuous evolution due to the development and improvement of new techniques economically affordable and environmentally friendly, as well as new biomaterials with high affinity to carry and coat bioactive compounds. Despite their potential as an efficient alternative to phytohormone treatments, encapsulation systems remain relatively unexplored to date. This review aims to emphasize the potential of phytohormone treatments as a means of enhancing plant stress tolerance, with a specific focus on the benefits that can be gained through the improved exogenous application of these treatments using encapsulation techniques. Moreover, the main encapsulation techniques, shell materials and recent work on plants treated with encapsulated phytohormones have been compiled.
不同人类活动导致的气候变化正造成不利的环境条件和失控的极端天气事件。这些恶劣条件直接影响作物种植区，因此，其产量（包括数量和质量）常常受损。寻求新的先进技术以使植物耐受环境胁迫并维持其正常生长发育至关重要。用外源植物激素进行的处理尤为突出，因为它们能减轻胁迫的负面影响并促进植物的生长速率。然而，田间应用的技术限制、可能的副作用以及确定正确剂量的困难，限制了它们的广泛使用。纳米封装系统已引起关注，因为它们能实现活性化合物的可控递送，并能用环保的壳生物材料进行保护。由于经济实惠且环境友好的新技术以及对携带和包覆生物活性化合物具有高亲和力的新生物材料的开发和改进，封装技术不断发展。尽管它们作为植物激素处理的一种有效替代方法具有潜力，但迄今为止，封装系统仍相对未被充分探索。本综述旨在强调植物激素处理作为增强植物胁迫耐受性手段的潜力，特别关注通过使用封装技术改进这些处理的外源应用所能获得的益处。此外，还汇编了主要的封装技术、壳材料以及用封装植物激素处理植物的近期研究工作。
