Module 2: CO2 Response Curves

Hear how plant physiologists use the LI-COR 6400XT to measure photosynthetic capacity. We cover how biochemical limitations prevent plants from continuously increasing photosynthesis in response to increasing CO2 levels.

Vow! well explained. simplified in details to make audience understand. Thanks for the video. Please keep uploading interesting simplified plant physiology concepts and experiments. I hope my comment would motivate you to work on your channel. thanks alot.

Love this stuff! From your chart, the rate of photosynthesis for a healthy set of variables including a steady temp of slightly less than 77 F (temps a guess on my part for purposes of example) seems to drop off at 600 ppm. Question - If at the point of drop off the temp was increased up to say 85 F while maintaining a good VPD rate for the current stage of growth and the proper EC (nutrient salts) feeding schedule would the photosynthesis rate continue to be linear and not drop off?
