种子成熟末期未经历明显的脱水过程，但此期间种子内营养物质的迅速积累以及种子脱落时种皮中较高的ABA含量、种皮和种胚中较低的GA_3／ABA值均对种子的耐脱水性和轻度休眠习性的形成起到重要的作用。

The results were showed that embryogenic calli were induced from young leaves, which were cultured on MS medium supplemented with 2,4-D 2mg/L and KT 0.2mg/L. For the proliferation of embryogenic calli, the suitable culture medium was MS+BA 8mg/L +NAA 1mg/L. The development and maturation of somatic embryo could be much improved by using the medium of MS+ZT 2mg/L or BA 5mg/L +IAA 0.2mg/L. For the induction of secondary somatic embryo from integral somatic embryo, the suitable culture medium was MS+KT 0.1mg/L+NAA 0.01 mg/L or MS+ZT 0.1mg/L+NAA 0.01 mg/L, the proliferation frequency is 214%, 256% respectively. The cotyledonary generated from somatic embryos of Aesculus hippocastanum L.

本文就欧洲七叶树的组织培养和体细胞胚发生以及植株再生进行了系统研究，主要结果如下：以植物细胞具有全能性的理论为依据，以欧洲七叶树幼嫩叶片为外植体，进行体细胞胚胎发生研究，研究结果表明，诱导愈伤组织的适宜培养基是MS+2，4-D 2mg／L+KT0.2mg／L，MS+BA 8mg／L+NAA 1mg／L有利于胚性愈伤组织的诱导和增殖，添加ZT 2mg／L或BA 5mg／L和IAA 0.2mg／L的MS培养基有利于体细胞胚发育和成熟，体细胞胚可直接诱导次生胚发生，MS+KT 0.1mg／L+NAA 0.01 mg／L或MS+ZT 0.1mg／L+NAA 0.01 mg／L培养基诱导效果最好，增殖频率分别为214％、256％。

In order to explore the mechanism of 'brumal jujube' of maturation and scenescence and ethanol accumulation, We not only studied the quality and the post-harvest physiological and biochemical changes of 'brumal jujube' after treatment with hormone during storage, but also investigated the effects of CAi (C027%~10%02+ 2~5%C02) and CA2:(7%~10%02, C02 2%) on the changes of fermentation volatiles, activity of enzymes , the kind and content of sugar and organic acid during storage in this paper. Firstly announced the reason of ethanol accumulation under higher C02 level and discussed the mechanism of ethanol accumulation during the end of storage.
