Myrtle (Myrtus communis L.) is a typical Mediterranean bush species, very spread in Sardinia.
Present interest in cultivating that species is caused by the increasing demand for berries and leaves to
produce the typical liqueur. Due to the high variability of biotypes in response to cutting multiplication, the
objective of that paper was to evaluate five south-Sardinian myrtle clones for their micropropagation
aptitude. For each clone, three multiplication media and four rooting media were tested; during
multiplication, proliferation rate of each clone on each medium was also calculated. Moreover,
acclimatization tests were carried out, either in growth chamber (with different types of light radiation), or in
green-house (in different periods of the year).
Based on proliferation rates, the most suitable multiplication medium was selected for each clone. As to
rooting, data were analysed with SAS software, providing the most suitable rooting medium for each clone.
Observations during acclimatization trials pointed out the requirement of a conditioned environment (either
growth chamber or green-house) in allowing an effective survival of plantlets from in vitro to in vivo
