متن کاملGenetic transformation of silver birch (Betula pendula) by particle bombardment.
We used in vitro callus and shoot cultures as target material for genetic transformation of silver birch (Betula pendula Roth) by particle bombardment. Cultivation of in vitro shoot cultures before particle bombardment and a long selection period, combined with a high concentration of selective agent after bombardment, led to the production of transformed plantlets that were stable, and no esca...
متن کاملPhysiological responses of Betula pendula Roth growing in polluted areas
