Warming effects on the responses of the maximum rate of Rubisco carboxylation (<i>V</i>_cmax), the maximum rate of photosynthetic electron transport (<i>J</i>_max) and the <i>J</i>_max/<i>V</i>_cmax ratio to foliar temperature (<i>T</i>_leaf) in 2010 (left panels) and 2011 (right panels).

<p>The filled circles indicate the warming plots and the open circles for the control plots. (A) and (B) area-based <i>V</i>_cmax; (C) and (D) area-based <i>J</i>_max; (E) and (F) N-based <i>V</i>_cmax; (G) and (H) N-based <i>J</i>_max; (I) and (J) the <i>J</i>_max/<i>V</i>_cmax ratio. Each data point is the average of 4 replicates.
