Phytohormones mitigate salt stress damage in radish

“…Regarding the total soluble solids content in the tubers, the application of polyamine led to a significant increase in this variable in plants subjected to severe salt stress compared to the other phytohormones and the control (Figure 3E). This suggests that polyamine plays a crucial role in regulating the accumulation of soluble sugars under adverse conditions (Silva et al, 2023). On the other hand, the application of cytokinin kept this variable constant in tubers subjected to both moderate and severe salt stress, with values higher than those observed in the control treatment, indicating its stabilizing effect on the maintenance of total soluble solids, especially under moderate and severe salt stress (Azzam et al, 2022).…”

“…Phytohormones play a vital role in how plants respond to salt stress, as they oversee the regulation of plant growth and facilitate adaptations in development because they contribute to perceiving salt stress signals and mediating the plant's defense system (Zhao et al, 2021). Jasmonic acid, salicylic acid, cytokinin, and polyamine have been reported as mitigators of damage caused by salt stress in plants (Naeem et al, 2020;Azzam et al, 2022;Silva et al, 2022a;Hudeček et al, 2023;Henschel et al, 2023).…”

“…Radish (Raphanus sativus L. -Brassicaceae) is classified as moderately sensitive to salt stress, and when exposed to high salt levels, it experiences a decline in photosynthetic capacity, growth, and ultimately yield (Henschel et al, 2023). Salicylic acid (Ulukapi et al, 2020;Mahdavian, 2023), methyl jasmonate (Henschel et al, 2023), gibberellic acid (Mishra et al, 2019), and polyamine (Çavuşoğlu et al, 2008) have been reported as mitigators of salt stress-induced damage in radish plants. Thus, the objective of this study was to assess the impact of phytohormone application in mitigating the harmful effects of salt stress on radish.…”
