Other claims from this paper (4)
- Observation Water vapour should be considered the primary source of water for seeds in unsaturated soils.
- Observation Most researchers recorded an approximately equal time to germination across soil water contents from field capacity to permanent wilting point.
- Observation Relative humidity remains near 100% in unsaturated soils.
- Observation Several experiments show timely germination of seeds in water vapour alone.
