By using convenient optical microscopy technique cotton fiber convolution parameters of draught and well-watered plants measured. It is shown that content of convoluted fibers for irrigated cotton significantly more than of drought cotton. Correlation between quality parameters (convolution characteristics, HVI (High Volume Instrument) parameters) two variety Gossypium barbadense and Gossypium hirsutum under draught and well-watered conditions observed. It has been shown that during different development stages dissolution of primary cell wall take place in cuprum-ammonium solvents more slowly than secondary cell wall. It is connected with structural transformation of cotton cell wall cellulose layers depend on stage its development.
