e0“Gibberellic acid (GA) in lanolin did not affect radial growth or cell expansion but strongly enhanced transverse cell divisions and, consequently, promoted internode elongation.”
Title

Jaime Kigel Botanical Gazette 1981. doi:10.1086/337189
Other claims from this paper (11)
- Intervention effect Decapitation reduced longitudinal and radial growth of the subjacent bean internode.
- Intervention effect Decapitation inhibited differentiation of vascular bundles and the cambial layer.
- Intervention effect IAA in lanolin restored radial growth in the decapitated internode.
- Intervention effect IAA in lanolin did not enhance elongation of the decapitated internode.
- Intervention effect GA in lanolin did not affect radial growth or cell expansion.
- Intervention effect GA in lanolin strongly enhanced transverse cell divisions.
- Intervention effect Applying IAA and GA together enhanced cell elongation.
- Intervention effect IAA inhibited GA-promoted cell divisions.
- Intervention effect Ethrel duplicated the effects of IAA.
- Mechanism The author proposes that GA and IAA jointly modulate internode elongation through cell division and cell elongation.
- Mechanism The author proposes that IAA action and its interaction with GA are ethylene-mediated.
