Gas exchange of sunflower leaves was measured across a wide temperature range from 3.9\u00b0C to 42.0\u00b0C. The conventional linear implementation generated highly dispersed pairwise intersections and unstable estimates of both \u0393* and\n                    <jats:italic>D<\/jats:italic>\n                    <jats:sub>L<\/jats:sub>\n                    , including some physiologically unrealistic negative\n                    <jats:italic>D<\/jats:italic>\n                    <jats:sub>L<\/jats:sub>\n                    values at low temperatures.
