- Intervention effect He-Ne laser irradiation increased chlorophyll a, chlorophyll b, and total chlorophyll.
- Intervention effect Low laser doses decreased superoxide free radical, hydrogen peroxide, and lipid peroxidation.
- Intervention effect Higher laser doses increased superoxide free radical, hydrogen peroxide, and lipid peroxidation.
- Intervention effect Ultraviolet radiation decreased photosynthetic pigments, shoot and root biomass, and root and shoot lengths.
