- Intervention effect Fluridone treatment decreased ABA levels in the root and mesocotyl growing zones of seedlings at low water potential, relative to untreated seedlings at the same water potential.
- Intervention effect Low water potential (-1.6 megapascals) shortened the growing zone of the maize primary root.
- Intervention effect Low water potential (-0.3 megapascal) shortened the growing zone of the maize mesocotyl.
- Intervention effect Fluridone treatment prevented most of the inhibition of mesocotyl elongation at low water potential.
- Mechanism Responses of root and mesocotyl elongation to ABA manipulation at low water potential involve large effects on cell expansion.
- Mechanism Maintenance of shoot elongation in fluridone-treated seedlings was not attributable to increased water or seed-reserve availability.
- Mechanism Root and mesocotyl growing zones show a developmental gradient in tissue responsiveness to endogenous ABA.
- Association The capacity of ABA to protect cell expansion at low water potential appears to decrease with increasing distance from the root apex.
- Association In the mesocotyl, ABA accumulation at low water potential appears to become increasingly inhibitory to expansion with distance from the meristem.
