Summary
A simplified and efficient encapsulation-dehydration protocol (a compromise between vitrification and encapsulation-dehydration) was presented for plant cryopreservation. During the encapsulation process, the apices precultured with 0.3 M sucrose for 16 h were osmoprotected with a mixture of 2 M glycerol plus 0.4 M sucrose for 1 h. These encapsulated apices were directly dehydrated with dry silica gel prior to a plunge into liquid nitrogen without pretreatment using 0.8 M sucrose for 16 h. This protocol produced much higher rates of recovery growth in the three plant species tested (wasabi, chrysanthemum, and mint) than those cryopreserved by the conventional encapsulation-dehydration and considerably reduced the time needed for the cryogenic procedure. This new protocol appears promising for cryopreservation of shoot apices and other explants.
