对腾冲红花油茶3个天然林种群和3个人工林种群的产量和脂肪酸组成进行了研究.结果为:腾冲红花油茶天然林和人工林种群间各产量指标、脂肪酸组成的差异较小;在天然林种群、人工林种群内却存在不同程度的变异,其中天然林种群内的茶油脂肪酸中的亚麻酸含量变异系数高达182.33%,单株产量变异系数高达96.16%;6个种群间产量指标存在极显著差异,脂肪酸组成存在不同程度的变异;相关性分析表明:油酸含量与亚油酸含量相关性不显著.总体上产量指标与茶油脂肪酸中的油酸和亚油酸含量存在较低的相关性,即可选育出果量和果质均较高的腾冲红花油茶新品种.以此提出在腾冲红花油茶的选育过程中应以天然林种群为主,人工林种群为辅.
Variation of Yield and Fatty Acid Content in Camellia reticulate
Choosing three natural communities and three artificial communities as study targets, the yields and fatty acid contents of Camellia reticulate were studied. The results showed that the differences of yield and fatty acid content between natural Camellia reticulate and planted individuals were not significant. Whereas, within three studied natural communities or three artificial communities, the variation in both oil yield and fatty acid content existed to different extents. Among the natural communities, the variation coefficient of linoleic acid and individual yield were as high as 182. 33 % and 96. 16 % respectively. There existed extremely significant differences among all the six studied Camellia reticulate communities on oil yield, variation of fatty acid composition existed as well. Correlation analysis demonstrated that the correlation between the contents of oleic acid and linoleic acid was low. As a whole, the correlation between oil yield and the contents of oleic acid and linoleic acid was low. Based on the this study, it was suggested that in selecting and breeding of Camellia reticulate, the natural community was the promising resource, and deserved to be given more attention than artificial communities.
