Turkey is the most important gene center of naturally grown Rosaceae family of hawthorn
(Crataegus spp.) species. Hawthorn grows naturally in mountainous areas, bushes and rocks
in our country and no cultural process is applied to these natural plants. Hawthorn contains
many substances such as flavonoids, vitamins and organic acids that are beneficial for human
health in fruit and flowers. In the present study the effect of different BAP (6-
benzylaminopurine) concentrations in in vitro propagation of four hawthorn genotypes (40-1,
50-1, 37-1 and 37-2) obtained from Apricot Research Institute Hawthorn Genetic Resource
Collection were investigated. MS (Murashige and Skoog) medium supplemented with
different concentrations of BAP (0.0. 0.5. 1.0. 1.5 and 2.0 mg/l) were used for in vitro
propagation of four hawthorn genotypes. All of the experiments established for
micropropagation of hawthorn plants were set up in randomized plots in a factorial design
with 3 replications. Shoot height (cm) and micropropagation rate were examined. The highest
of plant height was achieved in medium supplemented with 1 mg/l BAP for 40-1, 37-1 and
37-2 genotype, 0.5 mg/l BA for 50-1 genotype. The highest of micropropagation rate was
achieved for 40-1, 50-1, 37-1 and 37-2 genotypes in medium supplemented with 1.5 mg/l
BAP, 0.5 mg/l BAP, 1 mg/l BAP and 1 mg/l BAP respectively.
