“…For example, in comparison to G. hirsutum, G. barbadense fiber has less loosely-bound xyloglucan (Avci et al 2013) and pectin with a lower level of esterification near the onset of secondary wall deposition (Liu et al 2013). The density of crystalline cellulose (mass per unit volume) in the dried fibers of both species was similar (*1.52 g cm -3 ) (Peeters and De Langhe 1986). However, there are other indications of biophysical differences: during enzymatic hydrolysis of neverdried fiber with a fungal cellulase solution, G. hirsutum fiber released glucose more rapidly than G. barbadense fiber.…”

The mesoscale packing and crystal structure of cellulose microfibrils as well as temporal changes in cell wall composition and hydration during the development of cotton fibers from two species, Gossypium hirsutum and G. barbadense were studied using vibrational sum frequency generation (SFG), attenuated total refection infrared (ATR-IR), Fourier transform Raman (FT-Raman) spectroscopy and X-ray diffraction (XRD). The developmental stages analyzed (13-60 days post anthesis) included primary wall synthesis, transitional cell wall remodeling, secondary wall thickening via synthesis of nearly pure cellulose, and fiber maturation. ATR-IR and FT-Raman combined with principle component analysis revealed that fibers of both species undergo abrupt changes in the cellulose and matrix polymer contents during the transition to secondary cell wall synthesis. XRD revealed that cellulose crystal size and crystallinity increase similarly over time in both species. SFG analysis of fibers from un-opened bolls, which were stored in water then air dried, showed subtle differences between two species in the mesoscale ordering of cellulose microfibrils in the maturing secondary walls. In the samples of mature fibers dried on the plant after the boll split opened naturally, the difference in SFG spectra between species was negligible. Collectively, the results show that (a) SFG can uniquely reveal differences in cellulose fibril ordering in maturing cotton fibers before boll opening; and (b) illustrate the comparative usefulness of other commonly used spectroscopic analytical methods for cotton fiber analysis.

“…This could indicate that for this species the output of nucieotar material into the cytoplasm is more intense at this stage of development than for G, arboreum and G, barbadense. In fact, total volume and secondary wall volume, which are reliable parameters for characterizing fiber expansion and secondary wail cellulose (Peeters et al, 1986a), were greatest for G, hirsutum. No considerable changes in the behavior of the nucleolus were observed 20 days after anthesis.…”

Plant. 71: 436-440.Changes in nucleolar size and nucleolar vacuolation at early stages of fiber development and final fiber dimensions were determined for cotton of different species: Gossypium hirsutum L. cv. B49, Gossypium barbadense L. cv. Menoufi and Gossypiton arboreum L. cv. Vimar. Size of the nucleoius in combination with its vacuolation at an early stage of development was found to be clearly associated with the final result of fiber development.

“…Furthermore, the sub‐optimum night temperatures in the boll development process cannot be compensated by high day temperatures. The rate of cellulose synthesis, therefore, appears to be the key to cotton fiber structure40–50 and a useful factor in determining the location specificity of cotton varieties, although the weight‐molecular distribution of cellulose around the fiber axis has also been proposed to affect the tensile strength of cotton fibers 50. With the advent of open‐end spinning technology, the emphasis on breeding cotton varieties for increased staple length has reversed in favor of breeding types for increased tensile strength of fibers.…”

Cotton fiber cellulose synthesis and cellulose content at various post anthesis maturity stages of boll' development were studied in sixteen cotton varieties of Gossypium arboreum and Gossypium hirsutum species, grown in the 2001 crop year in New Delhi, under identical agro-climatic conditions. Cellulose content was estimated using Updegraff's method. Field matured seed cotton was harvested at the end of the crop season and ginned fibers were subjected to physical testing in an AFIS-HVI facility. X-ray orientation parameters were computed from the normalized azimuthal diffracted X-ray intensity scans of (002) reflections. Simple correlations were worked out among various parameters measured. Cotton varieties were indeed observed to vary in their synthesized cellulose content and such differences are genetically inherent.Varieties of Gossypium arboreum synthesized less cellulose compared to the Gossypium hirsutum cultivars, although the rate of cellulose synthesis within each variety, regardless of species, was observed to be practically uniform at any five-day interval. The range of variation in cellulose content was observed to be more than 260%. Uniformity ratio, HVI tenacity and average leaf area were positively correlated with cellulose content. X-ray angles of 40% and 50% correlated significantly with a negative cellulose content, (thereby) indicating an increased orientation of cellulose crystallites to the fiber axis, with a greater amount of cellulose synthesized.
