Studying Oat Plants Regenerated in Osmotic Selective Systems with Aluminum
In selective systems with aluminum and polyethylene glycol, callus lines of oat (Avena sativa L.) were obtained, and plantlets resistant to toxic ions and osmotic stress were regenerated. The comparative analysis of somaclonal variants derived in different selective systems was performed. The character and intensity of stress in vitro affected the duration of vegetation period, height, layering capacity, and seed productivity of regenerated plants, as well as the level of lipid peroxidation in leaves. The stress had no effect on the content of photosynthetic pigments and anthocyanes in the leaves of somaclones.
