Brief summary
It has been shown that a single irradiation of planarians by monochromatic red light from the LED array (λmax = 635 nm) in varying degrees increases the rate of growth of the head blastema of planarians, depending on the radiation dose. Maximum stimulation of regeneration observed at doses of 197.1 - 219 mJ / cm2. By increasing or decreasing the dose of light exposure the effect size decreases, up to its total absence. After changing the exposure time interval - before or after decapitation of planarians observed inversion of light effect. Instead of the stimulation we observed an inhibition of blastema growth. Broadband red light irradiation (600 - 750 nm) had no effect on the rate of planarian head regeneration.
Key words
