Comparative analysis of the cellulose measurement in fiber and sheave of different flax varieties was conducted by near-infrared spectroscopy and classical chemical method. Samples of fibers and sheaves have been obtained in field tests with plant growth regulators. Discovered difference between results of two compared methods was 0.1-0.8%. Applying of Apin-extra, Floravit and humic-fulvate complex (HFC) resulted in increase of cellulose content in the fiber and sheave at 5.0-11.8%. Floravit was the most effective biostimulator among others. It increased the cellulose content in fiber at 8.1-11.8% compared to control variant, 1.4-5.5% compared to variant with HFC and 0.5-3.3% compared to Apin-Extra. The method of near-infrared spectroscopy recommended as a reliable alternative to classical chemical methods for cellulose determination in flax fiber and sheave.
