Abstract: | Flow cytometry seed screen of mature seeds originating from several in vitro regenerated Hypericum perforatum L. somaclones and their seed progenies were used to screen the ways of reproduction of 4 subsequent generations of several somaclonal families and to search for the relation between the ploidy and prevalent mode of reproduction. The prevalent reproduction pathway of diploid plants was sexual reproduction. Seed samples of plants with higher ploidy levels showed an extensive variation in the mode of reproduction: BII and BIII hybrid formation and/or aposporous pseudogamy including parthenogenetic development of a reduced embryo sac. |
