Information About Author:

The incorporative effects of luminescent red radiation of low intensity, generated by correcting light polyethylene films and redundant ultraviolet-A radiation on morphogenesis of Arabidopsis thaliana (L.) Henh. of wild-type Ler and two light mutants hy3 and hy4 deficient in synthesis phytochrome B and cryptochrome 1 accordingly were investigated. Wild-type plants, cultivated under these correcting light films have no any changes in its development, while hy4 mutant exhibits increased development process and growth. Lethal effect of UV-A radiation was noted in the process of growing hy3 mutant, especially in the initial stage of true leaves development. Results from studies indicate regulatory interaction of low intensity red luminescent radiation and redundant ultraviolet-A radiation on stimulation and inhibition of plants growth and productivity
