Abstract

We aimed to evaluate the effect of light type in vitro culture of Eugenia involucrata. The treatments consisted of growing the species under light emitting diodes (LEDs) of different color spectra and fluorescent lamps. The highest average of plants establishment in the cultures under white and blue LEDs; under blue and fluorescent lamps, we registered the largest number of leaves; under blue, the largest number of shoots and under white, less bacteria contamination. When plants were under green LEDs, we obtained the worst results. Blue, red and white LEDs and fluorescent lamps influence positively in vitro propagation of E. involucrata.
