In vitro propagation of Heliconia standley Macbride
Journal Title: Biotecnología Vegetal - Year 2008, Vol 8, Issue 1
Abstract
The propagation of Heliconia sp. in Cuba is conceived by applying traditional methods, which are mainly based on sowing or planting rhizomes. Having a protocol for the in vitro culture would increase the yield and quality of the plants obtained. The aim of this study was to establish a protocol for in vitro propagation of H. standleyi. Experiments were conducted in each of the stages from establishment to acclimatization. The in vitro propagation of H. standleyi was achieved. For in vitro establishment, 2% of sodium hypochlorite, 20 min of disinfection and liquid culture medium were used. When using 2.0 mg.l -1 6-BAP and 0.65 mg.l -1 IAA, in the multiplication stage in semisolid culture medium, a 4.6 multiplication coefficient was obtained. It was demonstrated that explants should be higher than 3.0 cm to be transferred to rooting stage. A determining factor in the acclimatization stage to achieve a greater plant survival was the initial height of the explants (higher than 5.0 cm) to be sent to field after 45 days of culture.
