Matricaria chamomilla is one of the most important medicinal plants in the world, which has been widely used in the pharmaceutical, food, and cosmetic-health industries due to its bioactive compounds. This study aimed to investigate the interaction effects of light (blue, white, red) and different concentrations of silver nanoparticles (0, 10, 20, 30, 40 mg/L) on the activity of antioxidant enzymes in M. chamomilla under tissue culture conditions. The plants were kept in controlled conditions for seven weeks. The amount of total protein and the activity of antioxidant enzymes, including catalase (CAT), peroxidase (POD), superoxide dismutase (SOD), polyphenol oxidase (PPO), and ascorbate peroxidase (APX), were measured. The results of our study showed that the interaction effect of light and nanoparticles on the activity of antioxidant enzymes was significant. The highest activity of antioxidant enzymes was observed in the blue light treatment combined with a concentration of 40 mg/L of silver nanoparticles. In particular, the activities of SOD, CAT, and APX enzymes increased significantly under blue light, indicating the stimulation of the plant's antioxidant defense system in response to the oxidative stress caused by nanoparticles. Also, the total protein content reached its maximum value under blue light treatment and high concentrations of silver nanoparticles. In contrast, red and white light had a lesser effect on enzyme activity and protein synthesis. The findings of this study indicate that blue light as a photostimulator can significantly activate the antioxidant system of M. chamomilla together with silver nanoparticles. These findings can be used to optimize the tissue culture conditions of medicinal plants and increase the production of secondary metabolites with medicinal applications.
