Description
Summary:<p>Due to the economic and agronomic potencial that morti&ntilde;o (<em>Vaccinium floribundum</em> Kunth) has in Ecuador, the objective of this research was to establish <em>in vitro</em> propagation methods for this species by seed germination and by shoot growth from axillary buds. Modified Woody Plant Medium [1] (mWPM) was used, in which up to 60.7% of seeds germinated. A strong cytokine, trans-zeatin riboside, TZR (1 mg/l), combined with a-napthaleneacetic acid, NAA (0.05 mg/l), was used to subculture the <em>in vitro</em> germinated plantlets. The use of basal medium without hormones or with 2iP, 6-(gamma,gamma-dimethylalylamino) pu&shy;rine, allowed elongation and rooting of plantletss. The acclimatization of morti&ntilde;o plants has not yet been standardized, and further research is needed to find the conditions that are suitable for this process. To establish <em>in vitro</em> cultures by axillary buds, apical segments of the stem were disinfected and introduced in medium mWPM containing TZR, (7 mg/l) combined with NAA (0.1 mg/l). Growing buds were transferred to media with 2iP (3 or 5 mg/l) for propagation and elongation. This investigation is a preliminary study for the <em>in vitro</em> culture of morti&ntilde;o, setting the basis for future research with this species.</p>
