hormone - Opis:
- Experiments on somatic embryogenesis in selected spruce, fir and larch species were performed to determine if this method of micropropagation enables production of quality seedlings for forest nurseries. High frequencies of embryogenic callus in spruce (23-31%) and fir (29%) were achieved when mature zygotic embryos were used as explants, while in larches (36%) only when megagametophytes (endosperms with immature embryos) were used. The possibility of somatic embryogenesis initiation also from somatic embryos (resulting in secondary and third generation of embryogenic callus) indicate high efficiency of this method of micropropagation. The best results at all stages of somatic embryogenesis (good proliferation of embryogenic callus, high rate of embryo regeneration and their survival) were obtained for Norway spruce, European larch and some hybrid larches.
