Other claims from this paper (13)
- Intervention effect The optimum initiation concentration of 2,4-D was 4.0 mg/L for maximizing initiation efficiency.
- Intervention effect The optimum initiation concentration of 6-BA was 2 mg/L for maximizing initiation efficiency.
- Association The efficiency of mature somatic embryo maturation varied greatly with the basal medium and ABA concentration.
- Recommendation Using the DCR medium as the basal medium and 10 mg/L ABA was the judicious choice for maturation.
- Intervention effect Adjusting the maturation medium osmotic pressure improved maturation efficiency.
- Intervention effect Using sucrose as the carbohydrate source facilitated maturation.
- Intervention effect A low (<8 g/L) Gelrite concentration in the maturation medium facilitated maturation.
- Observation Optimal maturation selections were genotype-dependent.
- Recommendation Culturing more than 100 mg embryogenesis tissue per dish is needless.
- Recommendation The optimum pretreatment for embryogenesis tissue cryopreservation was proliferation medium with 0.4 mol/L sorbitol for 24 h, followed by 5% DMSO.
- Observation The study significantly improved somatic embryo initiation to a frequency of 0.56.
- Observation The study significantly improved embryo maturation efficiency to 1030 E/gFM.
- Observation The preculturing protocol recovered 1354 E/gFM after cryopreservation.
