The cotton hairs are the practically important example of single-cell epidermal seed trichome of plant kingdom. The objective of this study was to investigate in vivo morphology of commercial fibers for Central Asian cotton variety: Tashkent-1, 108-F G. hirsutum L., C-6030, C-6524 G. barbadense L. and Turfan gusa G. herbaccum at early stage their elongation. The fine structure of the primary cell wall surface of a cotton hairs and adjoining plasma lemma were studied by the replications-prints method by using optical and electron microscopy. The observations of the apical parts of the growing hairs on some ovary seeds, as well as the direct measurement of the rates of their growth on the cotton segments show that the process of the cell-hair growth has an oscillatory character and depends on the location of the hair on the ovary seed epidermis, on curvature of the apical part surface and the hair age. We can conclude, that using of replications-prints method, optical and electron microscopy has allowed to reveal a number of the new moments in a biology of cotton hair developing, to define more exactly real morphology of cotton hair at early growth stage, determine details of cellulose synthesis, cotton hairs mechanics and regularities of a hairs arranging in a cotton lobule, its screw-like twisted form etc.
