Fig. 1. (A) Typical fluorescence (F) emissions (400–800 nm) for the three species in this study, including corn (black, bold), soybean (gray), and maple (black). F (counts/second [c/s]) were produced using a 360-nm excitation wavelength, exhibiting distinct F features in the blue, green, red, and far-red regions. (B) F emissions from the three species significantly differed in the blue and green regions (F440 and F530, adaxial leaf surface): corn (black circles); soybean, Ks4694 (gray + symbols); soybean, Manokin (gray x symbols); and maple (black triangles).
