Abstract:
      In order to research the change rule of fatty acid composition and content in the growth and development of Sacha inchi seeds, the fatty acid composition and content of Sacha inchi seeds during 12 growth stages were determined, and the cell morphologies of Sacha inchi seed oil bodies in the kernel were observed by Zeiss Axio Imager. A1 microscope. The results showed that during growth and development of Sacha inchi seeds, the unsaturated fatty acid content increased gradually and reached 92.15% when Sacha inchi seed was mature, in which the total content of linoleic acid and linolenic acid was 8532%. However, the saturated fatty acid content decreased, the total content of palmitic acid and stearic acid was only 7.06% when Sacha inchi seed was mature. The cytological observation indicated that the peak oil conservation in Sacha inchi seeds was between sample 9 to sample 11, and the best picking period was after blooming for 120 d.
