Leaves of corn (Zea mays L.) and soybean (Glycine max L.) plants were examined in a set of four experiments conducted in the summer of 2001 at USDA in Beltsville, MD. Red edge reflectance spectra and red (R) and far-red (FR) fluorescence emissions were acquired for adaxial and abaxial leaf surfaces, in conjunction with foliar chlorophyll content, photosynthetic capacity (Amax), and C/N ratio. A red edge first derivative ratio was strongly related to chlorophyll content, Amax, and C/N ratio. R/FR fluorescence emission ratios also were related to Amax and C/N levels, and enabled species discrimination.
