Objective
The course aims to achieve the following objectives:
1. To provide an understanding of the productive processes in a Biofactory of forest species;
2. To develop mechanisms related to automation in in vitro propagation processes and
acclimatization of forest species;
3. Develop competence and critical capacity regarding the study and domestication of new
(native) forest species.
