Data were means ± SD of three replicates. C16:0 (Palmitic acid); C18:0 (Stearic acid); C18:1n7 (vaccenic acid); C18:1n9c (oleic acid); C18: 2n6c (linoleic acid); C18:3n3 a (linolenic acid); SFA/UFA (ratio saturated/unsaturated fatty acids); ω3/ω6 (ratio linolenic acid/linoleic acid); OY (oil yield). In same line, means with the same letter are not significantly different at 0.05 probability.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
