通过在培养基中添加单种抗生素或多种抗生素混合物,研究了抗生素对细菌污染的榆叶梅组培苗的影响。结果表明:当青霉素钠浓度300 mg/L、链霉素浓度100 mg/L 2种抗生素混合使用时,组培苗污染率相对较低、增殖率相对较高,且植株长势良好。 The effect of antibiotics on the bacterial contamination of Prunus trilobata tissue culture seedlings was studied by adding a single antibiotic or mixture of antibiotics in the medium. The results showed that when the penicillin sodium concentration 300 mg / L, streptomycin concentration 100 mg / L two kinds of antibiotics mixed, tissue culture seedling pollution rate is relatively low, the proliferation rate is relatively high, and the plants grow well.
