ABSTRACT
Because this tropical fruit is not so popular in Europe, we sis try he initiation of an tropic shrub of Psidium guajava it was possible to make, using them seeds from the matured fruit of guava. The fruit is originally from Egypt – Alexandria. Those seeds were dry and before using them, they were kept in sterile water few hours, after that it was performed the sterilization process, and they were inoculated in 4 different experimental variants.Because them germination process was start late, after 2 months from inoculation, observations were made to the level of the germinated seeds, didn’t shown any infections, but the best results were noticed only on variant V1 (BM basic medium - MS with BA (1 mg/l) + IBA (1 mg/l)), where the germination capacity it was more bigger.Finally, we did noticed that after the end of this experiment, the best medium culture for the generation of stemlets with many leaves is V1 and V3, but for the root development only V2 showed a very good result. Kept in good light intensity, humidity and optimal temperature conditions, the experiment showed good results, what made this research possible.
