Abstract

In this present study, we explored the effects of silver nitrate (AgNO3) on somatic embryo induction and the development from immature zygotic embryos in Manchurian ash (Fraxinus mandshurica Rupr.). AgNO3 played a minor role on in vitro embryo induction frequency and in the number of somatic embryos per explant. However, 1 mg Lā€“1 AgNO3 enhanced synchronization and significantly inhibited abnormal somatic embryo formation suggesting that AgNO3 might serve an important function in controlling the development of somatic embryos in Manchurian ash. Our results provided foundation for a future more efficient somatic embryogenesis and regeneration protocol.

Key words: Abnormality, Fraxinus mandshurica, silver nitrate, somatic embryogenesis, synchronization.
