Abstract:

Modification of the medium composition was a trial to improve germination and conversion in somatic embryos of Norway spruce. The mature embryos germinated for 1 week in the medium supplemented with either auxin (lAA, IBA, NAA - 0.05; 0.25; 0.1 or 0.5 pM) or gibberellin (GA3, GA4+7 _ 25; 50; 125 or 250 mg dm-3). The hormone-free medium used for the next 2 weeks of germination was enriched or not with activated charcoal (10 mg dm-^). The auxin applied in the medium did not affect embryo germination nor root and shoot growth. GA3 stimulated root and shoot growth in germinating somatic embryos, whereas the highest concentration of GA4+7 completely inhibited embryo germination.
