Matrix-scan 3D graphs for undamaged boll tissue. Panel A: Emission ranged from 320 nm to 585 nm and excitation ranged from 300 nm to 500 nm. The peak marked A emitted from 320 nm to 360 nm with excitation from 300 nm to 320 nm. The peak marked B emitted from 380 nm to 440 nm with excitation from 320 nm to 360 nm. Panel B: Emission ranged from 370 nm to 685 nm and excitation ranged from 350 nm to 500 nm. The peaks marked A and B seen in in Panel A were not included in Panel B, because the excitation range for Peaks A and B was not included. The peak marked C was for chlorophyll, which emitted from 660 nm to 690 nm with excitation 380 nm to 430 nm.
