Other claims from this paper (7)
- Observation Cyathea delgadii formed somatic embryos reproducibly and rapidly on hormone-free medium.
- Observation Somatic embryogenesis was induced in primary and secondary explants of Cyathea delgadii without exogenous plant growth regulators, in darkness.
- Observation Three morphogenetic stages of fern somatic embryo development were defined: linear, early and late embryonic leaf stage.
- Observation The transition from somatic embryo to juvenile sporophyte in Cyathea delgadii was quick.
- Observation After 9 weeks of culture, the efficiency of somatic embryogenesis in Cyathea delgadii reached 12-13 embryos per responding explant.
- Observation Spontaneous somatic embryos and callus production improved the effectiveness of somatic embryogenesis sevenfold in a 10-month culture.
- Observation Embryogenic competence is much easier to evoke in ferns than in spermatophytes.
