Technical Abstract: An examination of FT-IR vibrational band development in spectra of cotton fiber at different developmental dates (18 – 40 days post-anthesis; DPA) will be presented in this talk. Results from three cotton cultivars will be presented. Two of the cultivars are nearly identical genetic lines, which have exhibited significant differences in fiber strength and short fiber content. However, the third cultivar was chosen from a sufficiently distinct genetic line. Discussion will center on spectral changes for three key regions, 1) the OH and CH stretch region, 2800-2700 cm-1, 2) the OH bending region, 1800-1500 cm-1, and 3) the fingerprint region with multiple C-O vibrations, 1250-850 cm-1. A comparison of observed spectral changes to measured fiber quality measurements (e.g.; maturity ratio, micronaire, flat bundle strength) will also be presented.
