The aim of this research was to study the effects of light-emitting diodes (LEDs) and cool white fluorescent lamps on micropropagation of different genotypes of red raspberry (Rubus idaeus L.). The performance of actively growing in vitro shoots of seven red raspberry cultivars was evaluated during multiplication, rooting and acclimation phases under controlled growth-room conditions. Plantlets grown under fluorescent lamps showed better responses concerning the number of shoots and leaves and shoot length, whereas those grown under LED light displayed higher shoot dry weight values. Plantlets rooted under LED light exhibited longer roots while no significant differences were found in rooting percentages and number of roots per explant under both light conditions. Plantlets survival rates, fresh and dry weight of shoots after acclimation were not affected by exposure to different light quality during the rooting phase. Survival percentage after acclimation ranged from 73% to 100% depending on the genotype and significant differences were observed between cultivars for all the measured variables during this phase.
