Interpretive Summary: Cotton fiber consists of natural cellulose I component and its end-use qualities depend on the amount of cellulose deposited during the growth. The term fiber maturity has been used to describe the degree of cellulosic development or the secondary cell wall thickening of fibers. Useful information about fiber maturity is of value to cotton breeders and growers for cotton enhancement and to textile processors for quality control. Undoubtedly, current-in-use cotton maturity measurements can meet the expectations from very differing fiber researchers. However, one of challenges is how to provide accurate maturity information on limited cotton fibers from breeders. To this point, FTIR technique, being structure sensitive and capable of microsampling, was examined as a potential to be applied in the rapid, non-destructive, and routine determination of cotton fiber maturity and crystallinity grown in planta and in culture. A number of spectral interpretation strategies, namely principal component analysis (PCA) and simple algorithms, were attempted and the results were discussed.
