Carbenicillin prevented the development of mature somatic embryos, reduced early stage embryos by >90% and tissue growth by 50%. Cefotaxime had no effect on overall tissue growth, but reduced the development of early and mature embryos by 20% and 6680%, respectively. Carbenicillin should not be used for transformation of Sitka spruce.
Key words: Sitka spruce, somatic embryogenesis, antibiotic sensitivity
