Comparisons of fiber properties from developing MD52ne and MD90ne fibers. Developing fibers at nine different developmental time points (10, 13, 15, 17, 20, 24, 28, 33, and 37 DPA) and full developed fibers at 44 DPA were collected from NILs grown side by side in replicated fields in New Orleans, LA in 2013. Asterisks next to the time points denote statistical significance. a Fiber length. Average lengths of developing fibers at different DPAs were calculated from 30 replicates. b Crystallinity. Average crystallinity (CI _IR) was determined from six replicates of ATR-FTIR spectra. c Maturity. Average fiber maturity (M _IR) was determined from six replicates using ATR-FTIR. d Fineness. Three hundred fibers of 15 mm length were used for each replicate of gravimetric fineness analyses. Average fineness values were calculated from three replicates. e Bundle fiber strength. Average bundle fiber strength of developing fibers was measured from three replicates by Stelometer
