摘要:
元宝枫是中国重要的木本油料树种，具有重要的观赏价值和药用价值。本研究对元宝枫种子发育过程中脂肪酸含量的动态变化以及油脂积累与可溶性糖积累和蛋白质积累之间的关系进行分析。结果表明，油体和蛋白体在元宝枫花后80 d时开始发育，且后期数量均大量增多，直至填满整个细胞。元宝枫种子发育过程中，油脂含量整体呈现“上升-下降-上升”的趋势，其中油酸和亚油酸是2种主要的脂肪酸，且积累模式大致相同；蛋白质含量在种子发育过程中不断增加，在花后210 d达到最大值(161.18 mg/g)，且蛋白质积累与油脂积累呈显著正相关（P>0.05）。本研究结果为元宝枫育种和栽培管理提供了重要理论依据。
Abstract:
Acer truncatum Bunge is an important woody oil tree with ornamental and medicinal values in China. The dynamic changes of fatty acid content and the relationship of oil accumulation with soluble sugar accumulation and protein accumulation were analyzed during the development of A. truncatum seeds. The results showed that oil bodies and protein bodies were firstly observed at 80 d after flowering, and the number gradually increased until the whole cell was filled. The lipid content showed an upward-downward-upward trend in the seed development. Oleic acid and linoleic acid were two main fatty acids, and the accumulation patterns were similar. The protein content increased continuously during seed development and reached the maximum value(161.18 mg/g) at 210 d after flowering. Protein accumulation was positively correlated with the lipid accumulation (P>0.05). The results of this study would provide a theoretical basis for the breeding and cultivation management of A. truncatum.
