Other claims from this paper (3)
- Method / resource Adding a water deficit effect on meristem behaviour to the trophic competition model reduced the RMSE of organogenesis simulations to a third.
- Association The rate of phytomer appearance was strongly affected by plant trophic status and soil water deficit.
- Mechanism The decrease in meristem activity under soil water depletion does not result from source/sink imbalances.
