Embryogenic cultures were established from silver fir (Abies alba Mill.) female megagametliophytes with developing embryos and from excised mature embryos after pollination with Abies cephalonica Lond. or Abies numidica DeLann pollea The frequency of embryogenic callus formation was dependent on genotype, collection time, medium and explants used. The embryogenic callus initiation potential of megagamethophytes with developing embryos in both hybrids was higher in early July and dropped as the zygotic embryos matured. Excised cotyledonary embryos were less suitable for induction of embryogenic cultures. SH medium supplemented with 1mg/l BAP was the most efficient for callus induction and maintenance. Cultures were composed of early somatic embryos with an embryonal mass formed of highly cytoplasmic cells, rich in cell organelles and a suspensor built up by vacuolated, strongly elongated cells. Maturation of embryos was detected with the formation of bipolar structures with shoot and root apices. Nutrition reserves were observed in cells of embryos cultured on DCR medium containing 1 or 10 mg/l ABA. Cotyledon formation, hypocotyl elongation and low frequency germination occured following transfer of the embryos to the same medium without ABA.
