title: [Acquisition and study of callus tissue during cultivation of mazzard and strawberry anthers].
abstract: Anters of 7 varieties of Cerasus avium (2n=16) and Fragaria grandiflora (2n==56) were cultured on Murashige-Skoog's medium. Formation of the callus tissue was observed for only one variety of sweat cherry with a frequency of 3.1-20.6%. The number of haploid cells in first transfers varied from 22 to 44% in different strains. There were two rises of mitotic activity in the callus cells. Subsequent transfers caused an increase in haploid cells. Chromosome aberrations frequency was comparatively low. No cases of induced organogenesis on any modifications of the nutrient media were found.
