John Gamon's virtual seminar "The Photochemical Reflectance Index (PRI): an Optical Metric of Plant Stress" discusses how the photochemical reflectance index (PRI) provides an optical measure of dynamic plant pigment levels related to photosynthetic activity and stress. Dr. Gamon will Introduce the concept of PRI, illustrate its application for detecting photosynthetic downregulation and other related stress responses in plants, and show recent results obtained with Decagon's PRI sensors.

Great Explanation! thanks!

Regarding the sunflower experiments: A) Could you also decrease the LUE by lower levels of nutrients? B) if you had an indoor growth there would be no change in the sun angle (zenith or azimuth); thus the long term changes i.e. 40 minutes, could be better studied.

Great video. Any thoughts on when you will release the most recent PRI webinar?

Decagon Devices, Inc. Thanks! I think I was actually in the field installing PRI sensors when this webinar was live. Really appreciate it!

Hi, Congrats John Gamon for such a scientific contribution. I would like to know if there is any study related to the radiation curve of stress with the plant in environments with average light regime along the day, in indoor places. In affirmative case, would someone share the name of the article here with me?
