Furthermore, based on the hypothesis of origin of purple apricot ( Prunus dasycarpa), distance crosses between common apricot and myrobalan were conducted to survey the origin of purple apricot in the view of fertilization biology and molecular phylogenetics. 另外,基于前人关于紫杏起源的假说,我们还开展了普通杏和樱桃李的远缘杂交实验,从授粉生物学和分子系统学角度对紫杏的起源进行了探讨。
