种间杂交是形成新物种的重要途径。因一系列的生理、遗传障碍而成功率低。现代生物技术虽能以子房或胚培养提高种间杂交成功率,但克服杂交不亲和性使形成有效胚仍属首要问题。本文采用了几种理化因素处理杂交亲本和组织培养技术,试图提高杂交亲和性克服杂 Interspecific hybridization is an important way to form new species. Due to a series of physical, genetic barriers and low success rate. Although modern biotechnology can improve the success rate of interspecific hybridization by ovary or embryo culture, it is still the most important issue to overcome the incompatibility of hybridization to form effective embryo. In this paper, using several physical and chemical factors to deal with hybrid parents and tissue culture techniques, trying to improve hybrid affinity to overcome miscellaneous
