Interpretive Summary: Chemical, compositional, and structural differences within the fibers at different growth stages, as well as their physical properties and end-use qualities, have been investigated considerably through a number of well-defined protocols. Such knowledge is of value to cotton breeders and growers for cotton enhancement and to textile processors for quality control. Due to its direct, non-destructive, and rapid attribute, this study reports the utilization of attenuated total reflection Fourier transform Infrared (ATR FT-IR) spectroscopy method to acquire compositional and structural information of fibers as young as 10 DPA by the strategy of simple algorithmic analysis, and then to compare the secondary cell wall synthesis of fibers at various developing periods with a traditional and time-consuming assay method.

Technical Abstract: The knowledge of chemical and compositional components in cotton fibers is of value to cotton breeders and growers for cotton enhancement and to textile processors for quality control. In this work, we applied the previously proposed simple algorithms to analyze the attenuated total reflection Fourier transform infrared (ATR FT-IR) spectra of developmental im and TM-1 fibers as young as 10 DPA and further to correlate the secondary cell wall synthesis of fibers with a traditional and time-consuming assay method.
