EFFECT OF DIFFERENT CULTIVATION TECHNOLOGIES ON CORRELATIONS BETWEEN THE SELECTED WHEAT GRAIN QUALITY FEATURES AND THE CONTENT OF PHENOLIC COMPOUNDS

摘要

The main objective of this study was to determine the effect of cultivation technologies (extensive vs. high-input) on correlations between wheat grain quality parameters, such as falling number value, wet gluten content and grain hardness, and the content of phenolic compounds, such as total free phenolic compounds and alkylresorcinols. alt was found high values of correlation coefficient between falling number value and wet gluten, and among analysed groups of polyphenols. Grain hardness was associated with content of wet gluten and falling number values. Additional significant correlations were observed inside each cultivar. Determined technological value indices (falling number value, wet gluten content and grain hardness) were primarily dependent on the cultivation technology, whereas the contents of the phenolic compounds and alkylresorcinols were mostly related to the wheat genotype.
