Biological testing of light-correctional films in the conditions of covered ground at the growing of white cabbage

For the covered ground the authors developed the technique of testing of light-correctional films containing the photoluminescent phosphor with luminescence in red spectral region (λλ = = 625¼626 nm). On the seedlings of white cabbage of the Nadezhda variety it was shown, that a evaluation of morphometric and physiologo-biochemical indices permit to determine effect of light-correctional films, which don't depends from wave length, but is due to the intensity of secondary luminescent light at the same type of used photoluminescent phosphor. It was marked, that light-correctional films create in the construction of covered ground the favorable conditions for plants development and permit to reduce 8-10 days for growing of seedlings in regions of risky agriculture without use of additional lighting.
