The parameters were estimated by fitting predicted O2 consumption and CO2 production rates of pear tissue samples based on the respiration submodel (Equations 1–4) to measured data by means of a least squares procedure. Diffusion parameters were taken from Ho et al. [30],[31]. ±95% confidence limits. Indices skin, r and z refer to the position of the skin, along the radial direction and along the vertical axis of pear, respectively.
