Other claims from this paper (10)
- Observation Seeds at 10.3% moisture were intact and germinated at 98%.
- Intervention effect Further desiccation substantially reduced germination.
- Observation Most seed coats cracked after drying to 5.1% moisture.
- Observation Germination ability persisted after 12 months at 10.3% and 7.3% moisture.
- Observation At 5.1% moisture, germination ability was considerably reduced.
- Observation Cracked seeds were consistently fungus infected and failed to germinate.
- Intervention effect Nearly all disinfected embryos from cracked seeds germinated.
- Observation After very cold dry storage, 80 to 100% of disinfected extracted embryos remained germinable.
- Mechanism The authors attributed dry seed germination failure to cracking and subsequent fungal susceptibility, rather than embryo death.
- Mechanism Cracking appeared to result mechanically from differing water sorption isotherms between seeds and embryo parts.
