Abstract: (275 Views) |
African violet is one of the popular ornamental plants with high diversity, that is propagated through asexual methods due to the lack of a proper sexual reproduction method. Despite the great genotypic diversity in this plant, no study has been reported on the genotype dependency of its in vitro regeneration. In this research, to evaluate in vitro regeneration potential, fifteen different African violet ecotypes with prominent phenotypic differences were cultured on the optimized regeneration medium. The results showed that all the studied genotypes have the ability to regenerate on this medium and, except for two ecotypes, the rest were placed in three statistical groups close to each other. These results prove the preservation of major factors involved in regeneration potential in different genotypes of African violets over time. This conservation can be related to the need of this plant for alternative reproduction methods due to the lack of an accurate sexual reproduction system. However, the number of regenerated seedlings from each explant was highly different in various ecotypes, which could be due to the interaction of other environmental conditions in addition to hormones in the activation of genetic and epigenetic factors necessary to prime cell fate towards plant regeneration through one of the mechanisms of somatic embryogenesis or organogenesis. In general, it can be concluded that in the African violet plant, regeneration mechanisms have been preserved in all genotypes, however, their activation in different genotypes to increase the number of regenerants per explant is dependent on optimizing environmental factors.
