Title
Ethylene limits abscisic acid‐ or soil drying‐induced stomatal closure in aged wheat leaves

Other claims from this paper (7)
- Intervention effect Older leaves closed stomata less fully than young leaves during soil drying.
- Intervention effect 1-MCP partly restored ABA or drying induced stomatal closure in older leaves.
- Intervention effect Variovorax paradoxus 5C-2 partly restored ABA or drying induced stomatal closure in older leaves.
- Association Older leaf stomata were more ethylene sensitive than younger leaf stomata.
- Association Endogenous ACC concentrations did not differ between older and younger leaves.
- Association Ethylene emission did not differ between older and younger leaves.
- Mechanism Altered ethylene sensitivity likely explains weaker ABA and drying stomatal responses in older leaves.
