Other claims from this paper (9)
- Intervention effect In vegetative cotton plants exposed to ethylene for 4 days or less, GA3 increased the amount of abscission markedly.
- Intervention effect GA3 promoted abscission over a wide range of GA3 concentrations at near saturating ethylene levels (10 µl/liter).
- Intervention effect GA3 promoted abscission when Ethephon was substituted for ethylene.
- Intervention effect GA3 promoted abscission at locations not receiving direct application of GA3.
- Intervention effect The GA3-promoted magnitude of abscission was greater than that from auxin transport inhibitors or abscisic acid.
- Intervention effect Auxin characteristically inhibited leaf abscission in cotton.
- Mechanism Endogenous gibberellins may be involved in rapid abscission of apical leaves from vegetative cotton plants exposed to ethylene.
- Recommendation GA3 application may offer an additional option in agricultural manipulation of abscission and dehiscence.
- Intervention effect GA7 also promoted abscission, over a wide range of GA3 concentrations at near saturating ethylene levels.
