Abstract
The effect of maturation pretreatment on development and growth of Abies numidica De Lann. somatic embryos was studied. The most beneficial was pre-culturing on Schenk and Hildebrandt medium without growth regulator for 2 weeks. Dry mass accumulation of emblings was lower than that of seedlings after 50 d of culturing. Contents of microelements in seedlings were higher than in emblings, but macroelements contents were higher in emblings. Contents of chlorophyll a and chlorophyll b in cotyledons were higher in seedlings than in emblings while no qualitative differences were detected between the protein profiles of seedlings and emblings.
