Description of the eight genotypic parameters used in the calibration step and of the three additional parameters used for designing ideotypes.

Parameter name	Description	Boundaries
		Calibration		Ideotypes design
		Lower	Upper	Lower	Upper
phiMax [bar⁻¹ h⁻¹]	Maximum cell wall extensibility. Involved in cell expansion rate	1.0E-04	0.01	0.002	0.02
Lp [g cm⁻² bar⁻¹ h⁻¹]	Conductivity of the composite membrane for water transport from phloem to fruit cells	5.0E-04	0.4	0.02	0.6
nuM [gs h⁻¹]	Maximum sugar active uptake rate. Involved in the sugar active uptake calculus (Ua)	0.002	0.15	0.002	0.2
tstar [h]	Involved in the sugar active uptake calculus. The higher is tstar, later the active uptake begins to decrease	10	900	10	900
tauA [h]	Involved in the sugar active uptake calculus. The higher is tauA, the slower is the active uptake decreasing rate in the growth stage	5	900	72	900
tauS [h⁻²]	Involved in the calculus of the reflection coefficient of the composite membrane (sigmaP) which increases with tauS. sigmaP is involved in phloem mass flow	5.0E-06	1.5E-05	1.5E-06	2E-05
lp1 [g bar⁻¹ h⁻¹]	Pedicel conductivity for the water transport in phloem	5.0E-05	0.1	0.002	0.2
rxp [dimensionless]	Rxp = Lx/Lp = Lx1/Lp1. Lx and Lx1 have the same meaning as Lp and Lp1 but they refer to the xylem	0.1	0.6	0.1	0.8
s0 [g]¹	Initial fruit dry weight			0.019	0.086
w0 [g]¹	Initial fruit water weight			0.126	1.0
bssrat [dimensionless]¹	Involved in the soluble sugar concentration calculus. Ssrat = assrat^*t/24 + bssrat Ssrat is the ratio between soluble sugars mass and the total dry mass			0.043	0.22

1 = irrigation dependent parameter, optimized only for the ideotype design.

The parameter ranges used in the calibration step are based on literature data. The lower boundaries of phiMax, lp, and lp1 are set near to 0 for computational stability reasons; tauA, tstar, and tauS are based on experimental information on fruit development.
