光皮树果实生长发育及其脂肪酸积累研究

对光皮树果实大小、鲜干重、含水率、含油率及脂肪酸组成进行了研究，结果表明：光皮树果实在整个发育过程呈现“S”曲线变化，果实含油率最大可达到34．23％。果实发育初期含水率最高，而在果实发育后期主要是干物质的积累，含水率较低。在光皮树果实油中，硬脂酸含量最低，维持在2％左右，油酸亚油酸含量最高，不饱和脂肪酸含量在70％以上。整个发育过程，棕榈酸的含量一直降低，导致饱和脂肪酸的含量变化也是递减的。

Fruit development and fatty acid accumulation of Swida wilsoniana

The fruit shape, fresh and dry weight and oils-component changes of Swida wilsoniana in the whole development process were studied. The results showed that, the whole development process of Swida wilsoniana fruit was shown as an s-curve and the maximum oil content of Swida wilsoniana fruit was up to 34.23% after ripening. The moisture content was higher in the beginning, then the accumulation of dry matter was mainly concentrated in the late stage of fruit growth. In the fruit oil of Swida wilsoniana, the yield of stearic acid was low,which was around 2%. Oleic acid and linoleic acid contents were higher, while unsaturated fatty acid content was over 70%. In the development period, palmitic acid content tended to downward, resulting in the decrement of saturated fatty acid con- tent.
