Best Way to Perform Light Response Curves? The right protocol depends on the information you’re looking for!

Presented by Dr. James Bunce

11:00 AM EDT
The “best” way to acquire light response curves depends on the information you are trying to obtain. Complete curves can be accomplished with as little as two minutes between step changes in PPFD, but stomatal conductance values would not represent steady-state values, and sub-stomatal CO2 values would increase abnormally at low PPFDs. This may or may not present a problem, depending on the purpose of conducting the light curve.

About James Bunce, PhD
Dr. James Bunce built his first photosynthesis system as a graduate student 48 years ago and has been performing leaf gas exchange measurements ever since. He recently retired from a 40-year career with the USDA-ARS in Beltsville Maryland as an environmental plant physiologist. His most recent work involves predicting impacts of global change, especially rising atmospheric carbon dioxide concentration and temperature on photosynthesis.

Since his retirement, Jim has been working closely with PP Systems assisting in the development of rapid A/C i analysis with the CIRAS-3.
