Temperature Response Curves

Photosynthetic responses to temperature can be used to assess physiologic and biochemical changes in plantsincluding protein kinetics and membrane fluidity. Click here for more information on how the LI-6400XT controls temperature.

Temperature response of mesophyll conductance (gm) normalized to unity for measurements made by the constant J method (constant rate of photosynthetic electron transport, open symbols) and variable J method (closed symbols) at 2°C (Bernacchi, et al., 2002.) The line is fitted to all points. Simultaneous measurements of chlorophyll fluorescence and gas exchange were made on Nicotiana tabacum (tobacco).
