From an economic standpoint, pineapple (Ananas comosus) is one of the most important fruits in Colombia. A decade ago, the Perolera variety was the most cropped cultivar of the Santander department, however, the variety has been displaced considerably due to the lack of technical extension services and theintroduction of new varieties. This research project was carried out with the intention to conserve the speciesthrough the development of in vitro pineapple explants using the organogenesis technique. Meristemsthat have been extracted from the crown of the Perolera pineapple variety were used for this purpose. Four disinfectant treatments were evaluated by looking at the different kinds of disinfectant exposure times.The treatment that gave the best results in terms of contaminant-free explants was the T2: Commercialdetergent + Tween 80 for 8 minutes, ethyl alcohol at 70% for 1 minute and sodium hypochlorite at 1,5% over10 minutes, with a contamination rate of 7% and 93% of the explants thriving. For the establishment phase,it was found that the medium MS MEP1 with 100% solid salts supplemented with 2000 ul/L BAP - 1000 ul/L ANA - 1000 ul/L AIA and 500 ul/L thiamine enabled 90 % of the pineapple explants to continue developing four weeks after planting. Similarly, the medium containing 3000 ul/L of BAP for the multiplication phase permitted an average proliferation of 4.62 shoots with 9.12 leaves per shoot and a length of 2.25 mm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
