Embryogenic cultures of Araucaria angustifolia were induced from dominant and non-dominant zygotic embryos excised from immature seeds proceeding from three different genotypes and five harvest dates. Zygotic embryos were inoculated in inductive culture medium LP and BM supplemented with or without plant growth regulators 2,4-D (5 µM), BA (2 µM) and Kin (2 µM). The genotype of the mother tree and the developmental explant stage affected the induction frequency. In the maintenance phase, embryogenic cultures were maintained at continuous repetitive cell cycles every 20 days in semi-solid or liquid medium. In the maturation phase the culture medium was supplemented with different types and levels of growth regulators, osmotic agents, carbohydrates and... |
