"The objective of this work was to induce in vitro shoot regeneration as influenced by plant growth regulators and ascertain an effective method of polyploidy induction using colchicine and oryzalin in two diploid cultivars Gizela and Black Velvet Scarlet F1 of Pelargonium x hortorum L. H. Bailey. In both cultivars, benzyladenine (BA) significantly improved shoot regeneration compared to zeatin. The infiltration and the dip methods of explant treatment were used for polyploidy induction. Regenerants were analyzed using the flow cytometry (FCM). In GIzela and Black Velvet Scarlet F1, 10 tetraploids on the level of 2n = 4x were found by the infiltration method. The tetraploidy was determined by the dip method in 4 shoots of Gizela and 11 tetraploids were detected in Black Velvet Scarlet F1." . "RIV/00027073:_____/09:#0000593" . . "Pelargonium x hortorum L.
