e0“failure of the very dry seeds of Sterculia foetida to germinate was not due to embryo death from desiccation but to cracking increasing susceptibility to fungal infection upon rehydration.”

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.
- Association Cracking was strongly negatively associated with relative humidity.
- Mechanism Cracking appeared to result mechanically from differing water sorption isotherms between seeds and embryo parts.
