It is a promising option for safe, long-term storage of Musa germplasm.
The method involves 2-4 weeks preculture of proliferating meristems on a high sucrose medium. Surviving peristematic clumps are then excised transferred to cryotubes, and plunged into liquid nitrogen for rapid freezing (-196 ° C).
At this temperature, cell division and metabolic process stop and the plant material can therefore be stored without modification for a long period of time.
An ideal embryogenic cell suspension contains a high proportion of ells that are isodiametric and characterized by a relatively large nucleus, small multiple vacuoles and tiny starch and protein grains.
Cryopreservation is the most effective means available to secure the integrity of the collection over long term.
