Abstract

In order to supply the growing market demand for orchids (Epidendrum Lilas), is usually recommended the micropropagation technique, mainly, for the production of quality seedlings in a short time and in large numbers. Since, the propagation of this species is slow through conventional means, factors such as the phytoregulators and the light spectrum that may interfere in the effectiveness of this technique. The objective of the work was to evaluate different concentrations of cytokinin and the use of different light spectra in the in vitro propagation of orchid Epidendrum lilas. Two factors were evaluated: concentrations of benzylaminopurine (BAP): (1.0; 1.5; 2.0; 2.5 and 3.0 mg L^-1) and the light spectra: white, red, blue and green. After two months of establishment, the following characteristics were evaluated: plant height (H), number of leaves (NL), leaf length (LL) and shoots (S). The data obtained were submitted to analysis of variance and the means compared by the Tukey test (p
