The results of biochemical analysis indicated that the content of GA 3 increased and the content of ABA decreased in cotyledons during the breaking of epicotyl dormancy, and the contents of endogenous growth regulators changed only slightly in the endosperm. We suggested that cotyledons be a key part controlling the epicotyl dormancy in peony seeds.

生化测定结果表明：在低温打破牡丹种子上胚轴休眠过程中，子叶中的萌发促进剂GA3 含量明显升高，抑制剂ABA 含量显著下降；而胚乳中的各种激素含量则变化不大，胚轴中的激素变化无明显规律，因此认为子叶是控制牡丹种子上胚轴休眠的关键部位。

与epicotyl相关的网络解释 [注：此内容来源于网络，仅供参考]

epicotyl：上胚轴

胚轴由胚芽(Plumule)、上胚轴(epicotyl)、下胚轴(hypocotyl)、和胚根(radicle)所组成. 下胚轴与胚根的分界点通常不易区别. 子叶附著在下胚轴. 子叶的数目因植物种类而异. 大多数的双子叶植物皆有两片子叶. 裸子植物中除conifer 有较多的子叶之外,

epicotyl：胚轴

由胚性细胞组成,当种子萌发时,这些细胞能很快分裂,长大,使胚根和胚芽分别伸长,突破种皮,长成新植物体的主根和茎,叶,同时,胚轴也随着一起生长,成为幼根或幼茎的一部分.胚轴一般可分为上胚轴(epicotyl)和下胚轴(hypocotyl)两部分,
