摘要: 以甜樱桃红灯为材料,幼果用0.1%HgCl2进行消毒,在无菌条件下取出未成熟胚子叶进行诱导,在胚成苗后进行继代和生根培养。培养结果表明,以MS为基本培养基,在2,4-D为2.0mg/L时培养基上胚性愈伤组织诱导率较高,为53.7%;愈伤组织经过数次继代后转移至MS附加6-BA1.0mg/L和NAA0.1mg/L培养基上可诱导体细胞胚的形成,诱导率可达81.0%.体细胞胚在合适的培养基上可继续生长和增殖。

Abstract: Cultivars sweet cherry Hongdeng was used as the materials.An immature pterodia was taken from young fruit disinfected with 0.1% HgCl2.Shoot multiplication culture and rooting culture were conducted after emergence of seedlings.The result indicates that the embryogenic callus(EC) frequency was 53.1% at 2mg/L of 2,4-D added in MS medium,After subcultured for several times,somatic embryogenesis at high frequency(81.0%) was obtained on MS medium supplemented with 6-BA 1.0mg/L+NAA 0.1mg/L.Somatic embryos can keep on growing and proliferating on appropriate medium.

Key words: Sweet cherry, Callus, Somatic embryogenesis, Plantlet regeneration
