The effect of imidazol fungicides applied either individually or combined with N6-benzyl-aminopurine (BAP) on the multiplication of low vigorous sweet cherry rootstock Gizela 6 was studied. The commercial chemical SPORTAK 45-EC-450 was used as the source of imidazole fungicide. Some 19 medium types were studied over the multiplication phase. The media, containing different rates of prochloraz (PRO), BAP, IBA and GA3, included macro and micro salts according to Murashige and Skoog (1962) (MS). PRO was applied at 3 concentrations (1, 5 and 10 microM), either individually or combined with BAP (4.4 microM), IBA (5 microM) and GA3 (0.3 microM). Upon the second subculture, the parameters of shoot multiplication, multiplication index, and length and number of axial and lateral shoots were checked. Fresh and dry shoot weight was also evaluated. The obtained results suggest that PRO intensifes the effect of exogenous added BAP on the multiplication of Gizela 6 vegetative sweet cherry rootstock, whereas when combined with IBA, PRO has been reported to affect rhizogenesis.
