| Abstract:
At the Universidad Autónoma Metropolitana, plant tissue culture teaching requires species with a fast and effective response due to the limited courses duration and facilities. This situation is a challenge for us to find the suitable materials for our 11 week laboratory practices. We have developed a successful protocol for pitahaya micropropagation. In this paper, we report an experiment conducted to evaluate pitahaya shoots rooting and acclimatization ability in 3 agricultural substrata. There were no significant differences for both variables in perlite and tezontle treatments. Nevertheless rooting best results were obtained in tezontle (91.6%) while establishment were best in perlite (96.6%). Plant vigour were best in tezontle. The ability of this species for simultaneously be rooted and ex vitro adapted in four weeks allow us to offer a complete view of micropropagation and acclimatization process to our students. | |
