These two parameters can be derived from the widely\u2010used Laisk method as the intercept of linear regression lines fitted to net assimilation rates (A\n                    <jats:sub>net<\/jats:sub>\n                    ) vs. chloroplast CO\n                    <jats:sub>2<\/jats:sub>\n                    partial pressures (C\n                    <jats:sub>c<\/jats:sub>\n                    ) obtained at different low\u2010irradiance levels. However, photosynthetic theory indicates curvature in the A\n                    <jats:sub>net<\/jats:sub>\n                    \u2010C\n                    <jats:sub>c<\/jats:sub>\n                    relationship which conflicts with the use of linear relationships for analysis. We, therefore, systematically evaluated the limitations of the use of linear relationships across temperatures from 5\u00b0C to 40\u00b0C and quantified the sensitivity of errors in \u0393* and D\n                    <jats:sub>L<\/jats:sub>\n                    estimates to the selected C\n                    <jats:sub>c<\/jats:sub>\n                    range. We found that wide CO\n                    <jats:sub>2<\/jats:sub>\n                    ranges, especially when they exclude the expected \u0393*, can introduce substantial biases in parameter estimation with linear regressions, particularly at lower temperatures. This can lead to marked underestimates of \u0393*, and biologically unrealistic D\n                    <jats:sub>L<\/jats:sub>\n                    .
