Factors about embryo rescue of three hybridization crosses:Zixiang seedless Liming seedless,Zixiang seedless Crimson,Zixiang seedless Jingzaojing were studied.The results showed that the best embryo culture time for this three hybridization crosses was 52 days after Pollination.For the development of embryo,the best medium was ER,the germination rate of embryo in nitsch medium was higher than that of ER;Germination rate of embryos cultured at low temperature(7℃)was higher than that at normal temperature(24℃...
