In the process of our researches the most intensive reproduction of hawthorn in vitro was observed when adding cytokinin (in the range from 1.0 to 1.5 mg/l) to the nutrient medium, including 6-benzylaminopurine on the background of 0.01Ц0.1 mg/l of auxins (indole-3-acetic acid). The propagation coefficient increased as the 6-benzyladenine concentration in the medium rose to 2.0 mg/l, however the formation of vitrificational shoots was observed.
The morphogenetic activity depended on the parent plant genotype of the hawthorn morphogenesis in vitro and propagation coefficient on the phytohormones content in the nutrient medium, their balance and the propagated material genotypes.
Key words: genus, genotype, hawthorn, micropropagation, morphogenesis, nutrient medium.
