η	Resistance to carbohydrate diffusion between cells	(15), (16)	4360	day ml−1	23
μ0	Relative radial growth rate of cell at T0	(1)	0.0570	μm μm−1 day−1	23
ω	Normalised rate of cell-wall mass growth	(9)	19.4	mg ml−1 day−1	23
Ea	Effective activation energy for cell enlargement	(1)	0.374	eV	31

Calibration of η, ω, and K_m used predicted carbohydrate concentrations in cells 1, 13, and 22 and cell masses in cells 10, 13, and 22 (counting from the initial), μ₀ used the final ring width, E_a used the ring width response to temperature, and E_aw used the maximum density response to temperature.
