Other claims from this paper (6)
- Observation Three tillering phases were recognized.
- Intervention effect Tiller bud initiation was little affected directly by density.
- Intervention effect Growing tillers had no growth rate difference across densities.
- Intervention effect At higher densities fewer buds developed.
- Intervention effect Density affected the morphology of tillers that grew.
- Mechanism The authors suggest endogenous gibberellin may control tiller bud growth.
