Other claims from this paper (11)
- Intervention effect Removing the apex did not increase lateral bud sensitivity to applied benzyladenine.
- Intervention effect Preincubation in 1 μM benzyladenine did not mimic the decapitation-related response to high concentrations.
- Intervention effect Application of 1 μM benzyladenine stimulated bud growth to rates seen in decapitated plants.
- Intervention effect Bud growth declined sharply 12 h after benzyladenine withdrawal.
- Intervention effect Root removal or optimal or supraoptimal benzyladenine did not appreciably change lateral bud lag time after decapitation.
- Intervention effect Optimal or supraoptimal benzyladenine did not appreciably change lateral bud lag time after decapitation.
- Intervention effect Root removal did not appreciably change initial lateral bud growth rates after decapitation.
- Intervention effect Optimal or supraoptimal benzyladenine did not appreciably change initial lateral bud growth rates after decapitation.
- Mechanism The authors infer that decapitation may initiate new events detectable in the response to applied benzyladenine.
- Mechanism The authors infer that exogenous benzyladenine cannot bring about the decapitation-associated events.
- Mechanism The authors conclude that factors besides cytokinin limit bud growth in intact pea plants.
