| 摘 要： | 对江西省40株油茶无性系的主要脂肪酸组成及其与种实性状相关性进行研究,结果表明:(1)油茶无性系油酸含量在75.83%~85.91%间,平均为81.90%,亚油酸含量在5.43%~12.56%间,平均为7.40%;棕榈酸含量在5.27%~10.39%间,平均为7.94%;硬脂酸含量在0.42%~3.14%间,平均为1.66%。各无性系脂肪酸组成变异存在较大差异,变异系数由大到小依次为:硬脂酸(40.34%)、亚油酸(18.45%)、棕榈酸(16.43%)、油酸(2.49%);油茶无性系不饱和脂肪酸含量在86.50%~91.75%间,平均为89.30%,变异系数为1.48%;饱和脂肪酸含量在7.30%~12.45%之间,平均为9.61%,变异系数为13.35%;(2)相关性结果表明,油酸与亚油酸、棕榈酸呈极显著负相关,与单果重、果高、单果籽数呈显著正相关,亚油酸与单果重、果高呈显著负相关,这些为油茶良种选育提供了一定参考。

| Abstract: | The main fatty acid composition and its correlation with seed traits of 40 strains of Camellia oleifera clones in Jiangxi Province were studied.The results showed that:1,The oleic acid content of Camellia oleifera clones was between 75.83%and 85.91%,with an average of 81.90%,the content of linoleic acid was between 5.43%and 12.56%,with an average of 7.40%;the content of palmitic acid was between 5.27%and 10.39%,with an average of 7.94.%;stearic acid content is between 0.42%and 3.14%,with an average of 1.66%.There were significant differences in the variation of fatty acid composition among different clones.The coefficient of variation from large to small was:stearic acid(40.34%),linoleic acid(18.45%),palmitic acid(16.43%),oleic acid(2.49%);The content of saturated fatty acids in Camellia oleifera clones was between 9.61%and 12.45%,with an average of 9.61%and a coefficient of variation of 13.35%.The content of unsaturated fatty acids was between 89.30%and 91.75%,with an average of 89.30%and a coefficient of variation of only 1.48%.2,Correlation results showed that oleic acid was significantly negatively correlated with linoleic acid and palmitic acid,and positively correlated with single fruit weight,fruit height and single fruit seed number.linoleic acid was significantly negatively correlated with single fruit weight and fruit height,which provides a certain reference for the breeding of Camellia oleifera varieties. |
