“…Kaolin Kaolin is a mineral clay that dissolves readily in water, and when sprayed on plants, it forms a protective particle film. It has been used to reduce the impact of abiotic stresses (heat, drought) under greenhouse conditions by lowering the temperature of the canopy, minimizing the effects of water stress, and reflecting solar energy off the leaf surface [193]. However, the impact of kaolin application on crops has not been fully understood.…”

In recent years, the progressive escalation of climate change scenarios has emerged as a significant global concern. The threat to global food security posed by abiotic stresses such as drought, salinity, waterlogging, temperature stress (heat stress, freezing, and chilling), and high heavy metal accumulation is substantial. The implementation of any of these stresses on agricultural land induces modifications in the morphological, biochemical, and physiological processes of plants, leading to diminished rates of germination, growth, photosynthesis, respiration, hormone and enzyme activity disruption, heightened oxidative stress, and ultimately, a reduction in crop productivity. It is anticipated that the frequency of these stresses will progressively escalate in the future as a result of a rise in climate change events. Therefore, it is crucial to develop productive strategies to mitigate the adverse effects of these challenges on the agriculture industry and improve crop resilience and yield. Diverse strategies have been implemented, including the development of cultivars that are resistant to climate change through the application of both conventional and modern breeding techniques. An additional application of the prospective and emerging technology of speed breeding is the acceleration of tolerance cultivar development. Additionally, plant growth regulators, osmoprotectants, nutrient and water management, planting time, seed priming, microbial seed treatment, and arbuscular mycorrhiza are regarded as effective methods for mitigating abiotic stresses. The application of biochar, kaolin, chitosan, superabsorbent, yeast extract, and seaweed extract are examples of promising and environmentally benign agronomic techniques that have been shown to mitigate the effects of abiotic stresses on crops; however, their exact mechanisms are still not yet fully understood. Hence, collaboration among researchers should be intensified to fully elucidate the mechanisms involved in the action of the emerging technologies. This review provides a comprehensive and current compilation of scientific information on emerging and current trends, along with innovative strategies to enhance agricultural productivity under abiotic stress conditions.

Traditionally, the root system has been regarded as the primary component influencing citrus tolerance. Aerial tissues also play a crucial role in abiotic stress tolerance, as they are responsible for vital physiological processes, such as photosynthesis and transpiration. In addition, these tissues are directly exposed to various stress conditions, including extreme temperatures (heat and cold), high light irradiation, and ultraviolet (UV) exposure. In the current climate change scenario, optimizing both citrus rootstocks and grafted scions is crucial to ensure fruit quality and crop yield. Various approaches have been used to investigate the significance of aerial tissues, including in vitro systems, isolated aerial tissue growth, reciprocal grafting, and girdling. This review highlights recent research on the role of aerial tissues in citrus plants under various abiotic stress conditions. Studying and optimizing the genotypes used as scions in grafted citrus plants under abiotic stress conditions is crucial and may contribute to the development of new crop management strategies and breeding programs. Furthermore, this knowledge could be extended to other crops, enabling the development of more resilient and productive agricultural systems.
