sunflower seed oil

Sažetak
For determination of the composition of fatty acids of sunflower seed oil were used 44 male-fertile sunflower lines in various degrees of inbreeding, being the creations of the Osijek Agricultural Institute. Fatty acids were determined by Perkin-Elmer gas chromatography and the method of internal normalization of surfaces. The obtained data were used to calculate the aritmetic means, values of dispersion, coefficients of linear correlation and coefficient of determination. The objective of this research was to demonstrate the form of interactions among the ratios i.e., correlation of the oleic, palmitic stearic and linoleic acids. The correlation intensity was determined according to the Roemer-Orphal classification. Linear regressions showed negative and mean correlation between the palmitic and oleic acid (r=-0.43). The correlation between the oleic and linoleic acid was negative and complete (r=-0.97). The positive and weak correlation was established between the stearic and oleic acid (r=0.30). According to the coefficient of determination (R2=0.99) only 1% of the sum of the total deviations remained undefined by the correlation of the variables tested.
