e0“Preculture in liquid medium containing 0.2 M sucrose also had a significant influence on the initial response after cryopreservation, with first signs of regrowth resumption 3 days after thawing, compared to 24-25 days in control, non-precultured embryos.”

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.
- Observation Surviving olive explants continued active growth with the usual growth pattern.
- Intervention effect Sucrose-enriched preculture greatly increased cell proliferation in somatic embryos.
- Mechanism The authors propose that meristematic and proembryogenic cell features promote survival and explain higher recovery.
