| 中文摘要: |
| 为研究印加果种子生长发育过程中脂肪酸组成及含量的变化规律，分析测定了印加果种子在12个生长时期中的脂肪酸组成，并利用荧光显微技术对印加果种子发育过程中种仁细胞内油体进行了细胞形态学观察。结果表明：印加果种子在发育过程中，不饱和脂肪酸含量呈渐增趋势，至成熟时含量达92.15%，其中亚油酸和亚麻酸二者含量达85.32%；饱和脂肪酸含量整体呈下降趋势，种子成熟时棕榈酸和硬脂酸总含量仅7.06%；结合细胞学观察，从样品9～样品11时期为印加果种子油转化高峰期，最佳采摘期为开花后120 d之后。 |
| 英文摘要: |
| 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 8532%. 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. |
