Influence of increasing seed oil content on the fatty acid profile of hemp ( <i>Cannabis sativa</i> L.)
2010
Finta-Korpeľová, Z.
This paper reports changes in the fatty acid profiles of the hemp seed oil of two breeding populations, Kolaj and Fibrol, after five and seven years of selection for high oil content. While the original variety Kompolti had a 3:1 ratio of linoleic acid to linolenic acid, which has been claimed to be optimal for human nutrition, the selected population of Kolaj (improved Kompolti) shows a ratio close to 4:1.The highest ratio of increase (r.i.) was 1.45, determined for γ-linolenic acid in Fibrol (improved Fibrimon 21-63). Another significant change was the 0.49% (r.i. 1.21) increase in stearic acid in this variety, along with a 3.16% (r.i. 1.1) increase in total oil content. In Kolaj the 5.87% (r.i. 1.2) increase in oil content was accompanied by a 1.76 % (r.i. −1.28) decrease in palmitic acid and by decreases of 2.98% and 0.18% (r.i. −1.15 and −1.16), respectively, in the α- and γ-linolenic acid contents.
