Leakage quantification. An oven dried ear with a developed area of 43.2 cm2 was inserted in the chamber which was then flushed with various CO2 concentrations and flow rates. Leakage modified CO2 concentration in the chamber, and the difference with the set CO2 concentrations resulted in an apparent net photosynthesis (a). The later was corrected according to Eq. (1) with a diffusion coefficient k = 0.45: the corrected net photosynthesis (b) was nil at any CO2 concentration and flow rate. Values are the average ± standard deviation of six measurements
