Raf. was achieved using the encapsulation-dehydration technique. The highest survival rates after cryopreservation (up to 50%) were obtained when encapsulated apices were pregrown for 3 d either directly in liquid medium containing 0.5 M sucrose or in media with progressively increasing sucrose concentration from 0.3 to 0.75 M, desiccated to 20-25% moisture content and frozen slowly (0.5°C/min) from +20°C to -40°C before immersion in liquid nitrogen. Recovery of whole plantlets from cryopreserved apices took place directly, without transitory callus formation. (Résumé d'auteur) %$ 084VITRO ; 076AMEPLA07
