INVESTIGATHION OF FLAX (Linum usitatissimum L.) GENE POOLE ON RESISTANCE TO SOIL ACIDITY

N.V. Kishlyan, T.A. Rozhmina

The authors have been investigated the differentiation of samples of gene pool of L. usitatissimum on stability to adverse edaphic factors of environment. The influence of change of soil’s acidity on indicators of efficiency and quality of a flax fiber in connection with genotype was established. From various botanical groups the samples steady to acidic and neutral reaction of a soil solution was revealed. It is shown, that efficiency decrease on acidic soils is caused mainly by toxicity of ions of aluminum.

Key words: flax, gene pool, collection of samples, edaphic factors, resistance, reaction of a soil solution, aluminum tolerance.
