| 摘 要： | 对腾冲红花油茶3个天然种群和3个人工种群的产量和脂肪酸组成进行研究,结果如下:腾冲红花油茶天然和人工种群间各产量指标、脂肪酸组成差异较小;在天然种群、人工种群内却存在不同程度的变异,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:油酸与亚油酸含量相关性不显著,总体上产量指标与油酸和亚油酸含量存在较低的相关性,即可以选育出产量和质量均较高的腾冲红花油茶新品种;提出在腾冲红花油茶的选育过程中应以天然种群为主,人工种群为辅。 |
| 关 键 词： | 腾冲红花油茶 脂肪酸 变异 产量 |

| Abstract: | Three natural stands and three artificial populations of Camellia reticulate were invested and analyzed on their variance of yield and fatty acid composition.The results showed that there was little difference in yield and fatty acid composition between the natural stands and the artificial populations,but there was wide variation in yield and fatty acid composition for the natural stands and the artificial populations respectively.For example,the yield per plant was 96.16%in the three natural stands.There were significant differences in all the yield indexes among the 6 populations while there were statistically significant differences in few indexes of fatty acid composition.Statistical analysis showed that there was little correlation between oleic acid and linoleic acid contents while lower correlations were observed between yield and oleic acid and linoleic acid,suggesting that some new types with high yield and good quality in Camellia reticulate might be bred.In addition,this study proposed that selective breeding of Camellia reticulate should mainly focus on its natural population. |
