引言甜樱桃和酸樱桃栽培品种的杂交种子萌发率低,可在无菌条件下培养取出的胚加以克服。层积早熟品种未成熟的胚可显著增加实生苗的数量和长势(Zagaja,1961)。Hruby(1954)从欧洲甜樱桃×酸樱桃的杂交胚获得了60%实生苗,从欧洲甜樱桃晚熟品种获得70%实生苗。在我们的实验中,观察到由胚培 Introduction Sweet cherry and sour cherry cultivar hybrid seed germination rate is low, can be cultured under sterile conditions embryos removed to be overcome. Immature embryos stacked with precocious varieties can significantly increase the number and vigor of seedlings (Zagaja, 1961). Hruby (1954) obtained 60% of the seedlings from the hybrid embryos of European sweet cherry × sour cherry and 70% of the seedlings from the European sweet cherry late maturing varieties. In our experiments, observed by embryo culture
