Other claims from this paper (7)
- Observation Initially floret initiation and tissue expansion occurred simultaneously at the meristem surface.
- Intervention effect The duration of the initial simultaneous phase remained unchanged across light environments.
- Observation The rate of tissue expansion varied greatly across environments.
- Association Floret initiation rate depended on meristem initial size and tissue-expansion rate.
- Observation Afterwards floret initiation continued without tissue expansion, causing a rapid decrease of meristem area.
- Method / resource A set of equations was proposed to predict floret initiation rate and floret number from tissue expansion rates in the meristem.
- Mechanism The formalism demonstrated a role for tissue expansion in determining the final number of florets.
