Résumé
An efficient micropropagation protocol has been developed for Helianthemum bystropogophyllum Svent., an threatened species from Gran Canaria (Canary Island, Spain). Shoot tips and nodal segments isolated from seedlings were used as primary explants. Multiple shoot production was observed in MS medium supplemented with different concentrations of BA. Rooting was achieved in MS medium by adding IBA or without any plant growth regulators. An 82% survival rate was obtained in the acclimatisation process.
