Abstract
In vitro-cultured adventitious bud clusters of Guazuma crinita Mart. were successfully cryopreserved by the one-step vitrification method. Small segments (1.0-1.5 mm3) cut from adventitious bud clusters were exposed to a cryoprotectant mix solution containing (w/v), 25 glycerol, 15 sucrose, 15 ethylene glycol, 13 dimethyl sulfoxide, and 2 polyethylene glycol, at 25 °C for 15-60 min prior to storage in liquid nitrogen. After rapid warming (37 °C), the segments were treated with woody plant medium containing 40 (w/v) sucrose for 20 min at 25 °C, and then transferred to recovery-growth medium. High survival rates (about 80) were achieved without any cold hardening and/or pre-culturing treatments, and about 30 of the surviving cryopreserved explants regenerated plants.
