“…Severe salt stress led to a significant reduction in the fresh mass of tubers in all treatments (Figure 3D). The average fresh mass of radish 'Cometa' is 5 g (Teixeira et al, 2019), with all treatments reaching this value. However, the application of cytokinin and polyamine increased this variable in plants under moderate salt stress, while the application of salicylic acid maintained it stable compared to the respective control for each phytohormone.…”

“…Regarding the length of radish tubers, severe salt stress led to a significant decrease, except in plants that were subjected to gibberellic acid application (Figure 3B). The average tuber length of radish 'Cometa' is 27 mm (Teixeira et al, 2019), with all treatments reaching this value. Polyamine application also increased this variable in plants subjected to moderate salt stress.…”

Phytohormones play a pivotal role in regulating plant growth and responding to salt stress, aiding in signal perception and defense system mediation. With this, the objective of the present study was to assess the impact of phytohormone application in mitigating the harmful effects of salt stress on radish. Three levels of NaCl (0, 50, and 100 mM) and five phytohormones (jasmonic acid, salicylic acid, cytokinin, gibberellin, and polyamine) plus a control treatment (deionized water) were studied. The application of phytohormones such as jasmonic acid and cytokinin improved photosynthetic efficiency, and diameter, length, and total soluble solids content of tuber. Under salt stress conditions, plants showed adaptations in gas exchange, varying their rates of photosynthesis and transpiration. Furthermore, an effective balance between carbon assimilation and water loss was observed in some plants. The application of phytohormones counteracted salt stress, safeguarding chlorophyll, sustaining gas exchange, and promoting plant growth of radish. Consequently, use of phytohormones represents an alternative for radish cultivation under salt stress.
