EFFECT OF TREATMENT WITH PREPARATIONS CONTAINING HUMIC ACIDS ON THE OIL CONTENT AND FATTY ACID COMPOSITION OF BRASSICA NAPUS L.
The article analyzes changes in the fatty acid composition of spring rapeseed represented by Trapper and Siberian varieties after their treatment with «Huminatrin» and «Beres-8». The fatty acid composition of spring rapeseed cultivated in the Siberian region was studied by gas-liquid chromatography. The rapeseed contains 19 fatty acids with a chain length of 12 to 24 carbon atoms. The treatment with preparations containing humic acids caused different reactions in varieties. The Trapper variety showed a decrease in oil content after processing, while the Siberian variety showed an increase in oil content. It was found that treatment with «Huminatrin» and «Beres-8» caused an increase in linoleic and linolenic acids and a decrease in oleic fatty acids. The maximum content of linoleic and linolenic fatty acids was observed in seeds after their treatment with the «Huminatrin». Also the treatment with «Huminatrin» and «Beres-8» preparations of Trapper and Siberian varieties led to an increase in the concentration of limited fatty acids.
