Other claims from this paper (8)
- Association Inoculum density significantly affected regrowth rate after olive embryo cryopreservation.
- Association A significant effect of inoculum density on recovery percentage could not be inferred.
- Intervention effect Sucrose preculture significantly improved recovery after cryopreservation.
- Observation Liquid ECO medium with 0.2 M sucrose for 28 days gave the best cryopreservation results.
- Observation After that preculture, 90% of explants resumed embryogenesis at 12 weeks after thawing.
- Intervention effect Liquid medium with 0.2 M sucrose hastened regrowth signs to 3 days after thawing versus 24-25 days without preculture.
- Observation Surviving olive explants continued active growth with the usual growth pattern.
- Intervention effect Sucrose-enriched preculture greatly increased cell proliferation in somatic embryos.
