In parallel, plant physiologists studied leaf gas exchanges using the new method of infrared gas analysis and a leaf chamber where the net photosynthetic rates ranged from 10 to 13 μmol CO 2 ·m −2 ·s −1, with the conclusion that all terrestrial plants have the same photosynthetic capacities, that are light saturated at less than 50% of ...
