PRI—Why You Should Measure It

Learn the basics of the Photochemical Reflectance Index (PRI).

In this webinar, Dr. John Gammon gives an introduction to PRI and what it can tell researchers about xanthophyll cycle activity, carotenoid: chlorophyll pigment ratios, light-use efficiency, and plant stress. He also discusses remote sensing of PRI.
