Rev. colomb. biotecnol [online]. 2013, vol.15, n.2, pp.97-105. ISSN 0123-3475.  https://doi.org/10.15446/rev.colomb.biote.v15n2.41268.

The Phalaenopsis hybrids have a significant economic importance throughout the world, as ornamental flower or plant. It is because of its attractive flowers and its adaptation capacity into different environments. The different culture media in vitro are vital to improve the efficacy of germination, growing and development of the Orchids for commercial and research purposes. In this research, the most appropriated medium for in vitro propagation of Phalaenopsis hybrid was determined. At first, the seeds viability was evaluated by using tetrazolium test (TZ). The seeds were disinfected and cultivated by means of the syringe method. The viability percentage average was 92.2 % (P≤ 0.05: Tukey HSD), with a percentage of germination of 95.1 % (P≤ 0.05: Tukey HSD) in all the environments. The most efficient culture Medium for Phalaenopsis hybrid phenological development, at 16 weeks, was Murashige & Skoog (MS). Coconut water and pineapple juice were used as supplement showing statistically significant differences (P≤ 0,05: Tukey HSD), in comparison with the other culture media, contributing this way to the usage of organic components, which will be employed to improve the germination and development of the Phalaenopsis.
