%X Petiveria alliacea L. is a medicinal plant originating from the Amazon region. This study describes an efficient cryopreservation protocol for somatic embryos (SEs) produced from roots of P. alliacea based on the comparison of vitrification, encapsulation-dehydration, and D cryo-plate techniques. With the vitrification technique, SEs treated with PVS2 solution (0.4 M sucrose, 3.3 M glycerol, 2.4 M ethylene glycol, and 1.9 M DMSO) for 30 min displayed high viability (85%) and intermediate proliferation recovery (about 12 adventitious SEs produced from original SEs [SEs/SE] after 90 d of culture). With the encapsulation-dehydration technique, lower viability (70%) and very low proliferation recovery (about two SEs/SE) were achieved with cryopreserved SEs dehydrated for 10 min in a laminar air flow cabinet. The D cryo-plate technique led to high viability (85%) and proliferation recovery (19 SEs/SE) of cryopreserved SEs after 90 min dehydration. In the experimental conditions tested, the D cryo-plate method was the most efficient technique for cryopreservation of P. alliacea SEs.
