Other claims from this paper (6)
- Mechanism Root resistance can cause aboveground water deficits even in moist soil.
- Observation Root permeability per surface area varies among species and root parts.
- Mechanism Root permeability is sensitive to temperature, oxygen and salinity, suggesting living tissue contributes much of radial flow resistance.
- Observation Calculations based on maize roots predict the symplasm as the most likely radial water pathway.
- Observation Experimental evidence also favors the symplasm pathway.
- Observation Xylem longitudinal flow usually offers much less resistance than radial flow.
