Other claims from this paper (7)
- Intervention effect FAST and Burgeffs mineral media gave good germination and growth.
- Intervention effect Eg 1 performed better for tuberous species.
- Observation Twenty-five of 29 orchid taxa germinated.
- Observation The four nongerminating species belonged to Cephalanthera and Epipactis.
- Intervention effect Immature seeds germinated better than mature dried seeds.
- Intervention effect Cold treatment was not required for the named boreal or alpine species.
- Mechanism Juvenile embryos and a heterotrophic stage may explain latitude-independent germination behavior.
