"IN VITRO" PROPAGATION OF LAVANDIN: ETHYLENE PRODUCTION DURING PLANT DEVELOPMENT |

| Abstract:
We report here on ethylene production by lavandin tissue cultures during micropropagation and callus differentiation processes. Vegetative stem nodes and flower spikes proved to be successful micropropagation explants, with 100% regeneration on 0.2 mg/1 BAP medium. These explants showed analogous ethylene pattern and regenerated shoot number. Decreased amounts of BAP in the culture medium were associated with lower ethylene levels and lower regeneration rates. Ethylene production by calli from different sources was high on callus growing medium, but decreased progressively on shoot forming and shoot elongation media. In agreement with micropropagation results, the highest amounts of ethylene corresponded with the best organogenesis response. | |
