【Abstract】 Embryonic axis and cotyledon of immature and mature embryos were induced as explants for embryogenesis in Ginkgo biloba. Results showed somatic embryos could be induced only through embryonic axis and cotyledon of immature embryos. MK + NAA 1 mg·L -1 + 6_BA 1 mg·L -1 was the best medium for somatic embryogenesis from embryonic axis, and somatic embryogenesis rate was 45.28%. MK + NAA 1.5 mg·L -1 + 6_BA 1 mg·L -1 was the best medium for somatic embryogenesis from cotyledon, and somatic embryogenesis rate was 12.9%. The growth and development of somatic embryos were promoted by adding 10% coconut milk into MK, and 34.48% somatic embryos could develop into plants.更多还原
