Toward an Optimal Spectral Quality for Plant Growth and Development

In this video, Dr. Bruce Bugbee summarizes the dual effects of photon quality on photosynthesis and plant shape. Spectral quality has an enormous effect on shape, but the effect varies among species. Conversely, the effect of spectral quality on photosynthesis is nearly constant among species, but our definition of photosynthetic photons may need revision to include both far-red photons and UV photons between 360 and 400 nm.
