Abstract
The dependency of radicle elongation in Abies numidica somatic embryos on germination media has been studied. No significant differences were detected between the Murashige and Skoog (MS) and Schenk and Hildebrandt (SH) medium. The addition of 10 g dm−3 activated charcoal or 0.05 mg dm−3 indole-3-butyric acid (IBA) into both media had positive influence on embryo germination. Difference between activated charcoal and IBA effects were significant. The high rooting percentage (85 %) was recorded on half SH medium with 10 g dm−3 sucrose and activated charcoal. After IBA addition rooting percentage was increased to 95 %. During 7 months 73 % of plantlets survived transfer to soil and in 54 % of plantlets shoot growth was observed.
