摘要
Remarkable progress has been made in the development of systems for somaticembryogenesis in conifers since 1985. Currently however, it is still recalcitrant to inducesomatic embryo development from Pinus species. It is now only possible to obtain somaticembryos and plantlets from Pinus caribaea. P. lambertiana and P. tadea through in vitroembryogenesis. Of the three Pinus species which have expressed embryogenesis in explant-derivedcultures. only P. lambertiana has been successfully induced to produce somatic embryos frommature zygotic embryos.
