Measurements of photosynthetically active radiation (400--700 nm) and shortwave irradiance (ca. 300--2,000 nm) were made over a 14-month period at College Station, Texas. The proportion of photosynthetically active radiation changed with intensity of incident irradiance and length of photoperiod. Fo
