Investigation of the Role of Gibberellic Acid in Salinity Tolerance of Upland Cotton Plant

The salinity is the actual issue in the plant growth. It directly restricts the productivity of plants in the whole species. Using phytohormone(s) in seed priming is one of the most crucial treatment methods to protect plants from salinity. A plant hormone called gibberellic acid (GA 3 ) is essential for controlling plant growth and development, especially in stressful situations. Determining the potential of seed priming with gibberellic acid under salt stress was the main goal of our study. We investigated the effects of varying GA 3 and NaCl concentrations on the levels of chlorophyll a, b, and carotenoids in cotton seedlings of the Gossypium hirsutum L. Agdash-3 genotype. This study also showed the effects of different GA 3 concentrations on the dynamics of polyphenol oxidase activity, which is crucial for the metabolism of phenolic substances and their involvement in plants' defense response. This investigation demonstrates that gibberellic acid regulates antioxidant enzyme activity and sustains chlorophyll a, b and carotenoid contents during salt stress circumstances which enhances resistance to salinity in cotton plants.
