Other claims from this paper (8)
- Intervention effect Anoxia rapidly depolarized both bean hypocotyl membrane potentials.
- Intervention effect Re-aeration repolarized bean hypocotyl membrane potentials.
- Intervention effect Anoxia reduced bean hypocotyl growth rate by about 85%.
- Intervention effect Re-aeration restored bean hypocotyl growth rate.
- Intervention effect IAA aerosol hyperpolarized Vps in bean hypocotyls after about eight minutes.
- Intervention effect IAA increased bean hypocotyl growth rate to ten times the control rate after a delay.
- Mechanism Increased respiration-dependent ion pump activity at the outer parenchyma membrane explained Vps hyperpolarization.
- Association Bean hypocotyl growth rate correlated with ion pump activity as IAA concentration changed.
