Abstract:

The Lavandula genus belong to the family Lamiaceae and comprises 39 species of aromatic plants. Many species of this genus are grown both as decorative plants and for the essential oil extracted from flowers and leaves. Vegetative propagation of lavender plants is produced with very low yield. Numerous researches have attempted to identify a protocol for micropropagation of different species of lavender and these suggests that the most effective method is propagation from axillary or terminal buds. Our observations led to the following conclusions: the best reaction highlighted was callusogenesis followed by caulogenesis. Lavender callus formation was highlighted in the medium supplemented with 2,4 D in various concentrations. On various hormonal formulas, the callus generally has a good proliferative capacity, but no regeneration capacity of new shoots. The emergence of shoots is a phenomenon that occurred with low intensity, caulogenesis being observed only on media supplemented with a reduced amount of auxins, in the presence of BAP.

Keywords:

Lavandula stoechas, in vitro culture, caulogenesis, callusogenesis.
