Clonal propagation of myrtle can be successfully achieved by micropropagation and, for many reasons related also to this, it would be of interest to make a method available for medium-term conservation of in vitro cultures. In our work we investigated the effect of low-temperature storage on the survival and proliferation capacity of microshoots. The influence of pre-treatments with abscisic acid and of conservation on mannitol-containing media were also investigated. It was found that myrtle can be easily stored for at least 6 months at 8ºC, recovering its proliferation capacity after this period.
