Other claims from this paper (8)
- Association Post-thaw viability of cassava callus clumps depended on the duration of cryoprotection on 0.3M sucrose.
- Intervention effect Cassava callus in a cryoprotective medium containing only ABA increased callus proliferation.
- Intervention effect Sucrose with low ABA concentrations (5-10 mg/l) in the cryoprotective medium decreased callus proliferation.
- Intervention effect Sucrose with low ABA concentrations (5-10 mg/l) in the cryoprotective medium resulted in post-thaw viability and/or embryogenic competence after cryopreservation.
- Intervention effect At the higher ABA concentration of 20 mg/l, post-thaw viability of cassava callus was completely lost.
- Intervention effect Cassava callus clumps pre-treated with low ABA concentrations with sucrose gave significantly higher plant recovery than sucrose-only pre-treated clumps.
- Intervention effect Plants recovered from cryopreserved cassava callus clumps were phenotypically similar to those from non-cryopreserved clumps.
- Recommendation Cryopreservation of cassava embryogenic calli is a feasible option for long-term conservation of crop genetic resources.
