摘要
测定了橄榄形、桃形、脐形、球形小果油茶的果实性状、含油率及脂肪酸组成,分析了其果实性状与含油率、脂肪酸组成间的相关性。结果表明:小果油茶籽含油率与果形有关,橄榄形果的果纵径、果形指数和鲜果含油率均大于桃形果、脐形果和球形果,但其鲜出籽率却低于其他3种果形。4种小果油茶籽油中,油酸含量的顺序为橄榄形果﹥桃形果﹥脐形果﹥球形果,而多不饱和脂肪酸含量的顺序为橄榄形果﹤桃形果﹤脐形果﹤球形果。相关性分析表明,小果油茶籽油中的油酸、亚油酸、多不饱和脂肪酸、单不饱和脂肪酸、饱和脂肪酸含量分别与果纵径和果形指数呈显著或极显著相关,说明小果油茶籽油脂肪酸组成与果形有关。
The fruit characters, oil contents and fatty acid compositions of Camellia meiocarpa with different fruit shapes were determined, and the correlation among them was analyzed. The results showed that the seed oil contents of Camellia meiocarpa were related with their fruit shapes. The fruit length, fruit shape index, oil content of fresh fruit of olive shaped fruit were the highest, but the fresh seed rate of olive shaped fruit was lower than the other three kinds of fruit shapes. The content of oleic acid in four kinds of fruit shapes de- creased from the fruit of olive shaped, peach shaped, umbilical shaped to spherical shaped, but the content of polyunsaturated fatty acids increased with an opposite order. The correlation analysis showed that the contents of oleic acid, linoleic acid, polyunsaturated fatty acids, monounsaturated fatty acids and saturated fatty acids of Camellia me/ocarpa seed oil were significantly correlated with the fruit length and fruit shape index, which indicated that fatty acid composition of Camellia meiocarpa seed oil was related with the fruit shape of Camellia meiocarpa.
