PRODUCTIVITY OF POTATOES MICROPLANTS IN VIVO GROWN UNDER THE ACTION OF DIFFERENT LIGHTNING SPECTRA

It has been established that the use of additional lightning by phyto LEDs undercultivation of potatoes microplants provides a positive effect on the survival and productivity ofpotatoes microplants in open ground conditions. Depending on the type of potato and thedifferent lighting spectrum, the survival rate of potatoes microplants was 66–86 % with thesurvival rates in the control 53 – 77 %; an increase in the multiplication factor of plants by 0.5 –0.8 units, depending on the type of potato and the different lighting spectrum, an increase in theaverage weight of the clone by 5.02 – 19.95 %, depending on the variety.
