摘要:: 以油用牡丹品种‘凤丹’为试材，记录了蓇葖果和籽仁不同发育时期的形态及质量，并利用GC-MS测定脂肪酸含量，分析了后熟对脂肪酸含量和成分的影响，以期为牡丹籽粒收获和脂肪酸生产提供指导。结果表明：籽仁发育过程可分为籽仁发育初期、籽仁快速生长期、籽仁发育定型期和籽仁成熟期4个时期。未经后熟处理的情况下，授粉后120 d时含油量最高，之后下降。后熟处理显著提高了籽仁的不饱和脂肪酸（油酸、亚油酸和α-亚麻酸）及总脂肪酸含量，其中100 d，后熟30 d的脂肪酸和不饱和脂肪酸含量最高，因此100 d采收后熟30 d是较佳的采收组合方式。研究结果对油用牡丹高产栽培具有重要指导意义，也为研究后熟机制奠定了基础。

Abstract:: The oil-used tree peony cultivar ‘Feng Dan’ was used as experiment material，and the effect of post-ripening on the content and components of fatty acids was analyzed by observing the morphology and weight of follicle and seed at differently developmental stage in order to provide guide for peony industry.The development processes were composed of the early formation stage，rapid growth stage，the developmental setting stage and mature stage，respectively.Under the non-post-ripening condition，the highest content of fatty acid was found in 120 days after pollination，and then followed by decline.Post-ripening treatments significantly increased the contents of unsaturated fatty acid and the total fatty acid，among which the contents of unsaturated fatty acid and the total fatty acid were the highest in 100 days after pollination and 30 days post-ripening.Therefore，the combination of harvesting after pollination 100 days adding post-ripening 30 days was a better way.The research results had important guiding significance for high-yield cultivation of oil-used tree peony and provided the theoretical basis for studying the mechanism of post-ripening in tree peony.
