Other claims from this paper (14)
- Intervention effect Decapitation released lowermost lateral-bud growth.
- Intervention effect IAA on the cut surface fully restored bud inhibition.
- Observation Uracil tracer was distributed in stems across experimental seedlings.
- Intervention effect Decapitation and IAA showed no consistent difference in stem uracil tracer distribution.
- Intervention effect Decapitation rapidly increased lateral-bud uracil tracer content beyond promoted growth.
- Intervention effect IAA fully suppressed this lateral-bud uracil uptake.
- Intervention effect A TIBA stem ring suppressed IAA action on bud growth.
- Intervention effect A TIBA stem ring suppressed IAA action on uracil tracer uptake.
- Intervention effect A TIBA stem ring suppressed IAA tracer movement down the stem.
- Intervention effect TIBA at the bud base did not prevent IAA action on growth.
- Intervention effect TIBA at the bud base did not prevent IAA tracer movement into the bud.
- Intervention effect Gibberellic acid caused a smaller, barely significant growth increase additive to kinetin.
- Intervention effect Neither kinetin nor gibberellic acid affected uracil movement into buds.
- Mechanism The findings most support auxin suppression of phloem differentiation in bud vascular supply.
