The world is currently entering challenges to face climate change and find alternative means to combat the oxidative stress resulting from it. The study aims to reveal the role of amino acids in combating oxidative stress resulting from exposing strawberry seedlings to ultraviolet rays (UV-C). The experiment included two factors, the first is the concentrations of amino acids, which include (v/v) (%0%, 0.012%, 0.024). The second factor includes periods of exposure to UV-C rays, which are min/h (0,15, 30 ,60). The seedlings were sprayed with the above concentrations, then exposed to different time periods of UV-C rays, and then the seedlings were transferred to the field to monitor growth and take the required measurements. The results concluded that amino acids significantly affected most of the studied traits at a 5% probability level, except for the survival rate, leaf area of the plant (cm), number of leaves, and the percentage of potassium element. As for the period of exposure to UV-C rays, it significantly affected all traits except for the nitrogen and potassium ratio in the leaves of the plant. The interactions between amino acids and periods of exposure to UV-C rays were significant in all studied traits except for chlorophyll content and potassium content in the leaves. We conclude from our research that amino acids have contributed to protecting the plant against oxidative stress resulting from ultraviolet rays, and that the rays did not cause the death of the plant, as the plant showed resistance against UV-C rays up to a full hour. Therefore, we recommend using amino acids to combat oxidative stress.
