- 摘要:
- 以冰糖橙胚性愈伤组织为试材,研究了琼脂及Gelrite 2种凝固剂对愈伤组织增殖、胚状体诱导、芽诱导及生根的影响。结果表明:以琼脂为凝固剂的培养基有利于提高胚性愈伤组织的增殖率,以Gelrite为凝固剂的培养基有利于胚状体诱导、芽诱导和生根。因此,在愈伤组织增殖过程中可使用琼脂,在体细胞胚状体诱导、芽诱导和生根阶段可使用Gelrite。
- Abstract:
- Taking embryogenic callus of Citrus sinensis L.Osbeck cv.Bingtang as initial explants,the effects of two types of gelling agents,agar and gelrite on the callus proliferation,somatic embryoid induction,bud induction and rooting in vitro was studied.The results showed that the culture medium prepared with agar was helpful for improving the proliferation rate of the embryogenic callus,and the culture medium prepared with gelrite facilitated somatic embryoid induction,bud induction and rooting of the embryogenic callus.Therefore,agar may be used during the process of callus culture,and it may be more reasonable of using gelrite as a gelling agent at the stages of somatic embryogenesis,bud induction and rooting.
