Parameter values for the simulations

	Potential fruit weight (g dm)	Fruit-growth duration (d)	Flower appearance rate (d−1)	Source strength (g dm d−1)	Vegetative sink strength (d dm d−1)	Threshold source : sink ratio for fruit set
Default	8	60	0·5	2·4	1·9	0·5
Sensitivity analysis	4, 18	57, 70	1	2·2, 2·6	1·6, 2·9	1
Small-fruited cultivar	4	57	1	2·2	1·9	0·5
Large-fruited cultivar	18	70	0·5	2·6	1·6	1

The first line gives the default parameter values. The second line gives the parameter values used in the sensitivity analysis. One parameter was changed, while keeping the other parameters at the default value. Small-fruited and large-fruited cultivars represent the parameter combinations for the simulations with realistic parameter combinations.
