The induction of microspores dedifferentiation and reclaim of sporophytic development is a complex process, dependent by a lot of factors, including pretreatment conditions and the genotype peculiarities. In results of application various experimental variants, distinguished by pretreatment schemes and nutrient media, had been obtained androgenetic positive response for barley cultivars (Galactic, Sonor, Unirea and Stralucitor). The embryogenic structures derived from in vitro anthers culture present different ultrastructural aspects in dependence of proliferation capacity and further development. In realization of androgenic potential, an important role it is found for organelles of energetic systems: plastids and mitochondria, proving cytoplasmic factors involved in establishing embryogenic ability. 9 references, 4 figures. |
