In the presence of the ionic liquid [bmim]Br/AICl3 as green reaction medium, methyl 12-benzoyldehy-droabietate was synthesized through Friedel-Craftsacylation r
甘蓝型油菜是由白菜型油菜和甘蓝杂交,染色体自然加倍进化而来的异源四倍体。在长期进化和驯化中,甘蓝型油菜基因组与其亲本种存在很大差异。开展甘蓝型油菜与甘蓝远缘杂交,能达到相互间转移一些特殊性状,拓宽遗传基础的目的。本文通过甘蓝型油菜与甘蓝杂种后代的细胞学分析,期望为甘蓝型油菜和甘蓝间相互转移性状提供理论依据。研究结果如下：1、甘蓝型油菜与甘蓝杂交亲和性分析本研究以甘蓝型油菜×甘蓝为正交,进行正反交测
