In vitro establishment of Heliconia rauliniana (Heliconiaceae)

Abstract: The great interest for heliconias by the external market has placed this crop in a prominent position in the flower production chain. The small offer of healthy seedlings, however, the expansion of this activity. The presence of endophytic microorganisms such as Pseudomonas sp. represents an obstacle even for the evolution of heliconia tissue culture studies. Stem apices of Heliconia rauliniana were inoculated and analyzed in vitro to investigate the presence of endophytic microorganisms. An antibiotic analysi… Show more

“…The stem apexes were submitted to inoculation in semi-solid (2.0 g L -1 Gelrite), MS culture media (Murashige & Skoog, 1962), supplemented with Morel vitamins (Morel & Wetmore, 1951), saccharose (30.0 g L -1 ), 6-benzyladenine (1.0 mg L -1 BAP), pH adjusted to 5.8 in addition to 500 mg L -1 of sodium cefotaxime, for control of endophytes (Rodrigues, 2005). The explants were incubated at a mean temperature of 26ºC and a photoperiod of 16 hours of light.…”

“…A cultura em estudo também pode ter influenciado o resultado, uma vez que, apesar de serem da mesma ordem Zingiberales, não houve dificuldades com bananeiras no desenvolvimento in vitro, o que não ocorreu com as helicônias, cultura que tem altos índices de oxidação (DIAS E RODRIGUES, 2001;RODRIGUES, 2005).…”

“…O Estado do Rio Grande do Norte desenvolve estudos com micropropagação convencional e aclimatização de helicônias (DIAS E RODRIGUES, 2001;RODRIGUES, 2005e RODRIGUES et al, 2005, visando atender à crescente demanda por mudas sadias. Apesar do emprego da cultura de tecidos não ser difundida e ainda estar em desenvolvimento para algumas espécies de helicônias, o custo de produção deve ser avaliado para viabilizar o comércio dessa muda.…”

“…Helicons have a subterraneous rhizome from which new buds are commonly removed for propagation (Castro, 1995), although this vegetative propagation system yields reduced number of plants and offers serious risks of pest and disease dissemination. Micropropagation has emerged as an important alternative for providing large-scale production of helicon plants with high standards of quality, but the micropropagation of helicons via shoot tips presents problems linked to endophytic contamination that can limit explant development (Nathan et al, 1992;Atehortua et al, 1999;Dias and Rodrigues, 2001;Rodrigues, 2005) so that the use of floral explants may represent a viable alternative . Plant genetics and biotechnology is highly dependent on the use of in vitro culture techniques, and among the various systems available, somatic embryogenesis offers the opportunity for the production of true-to-type plants by clonal propagation and is a useful tool for basic research on totipotency and the fundamental processes of plant morphogenesis (Gaj, 2004).…”
