| Summary: | In this study, a wild relative of Citrus, Severinia buxifolia, was subjected to
tissue culture treatments in order to identify the best medium for plant regeneration
of this species. This research was carried out due to its range of uses and because of
its potential to be a rootstock species that is tolerant to boron. Different sources of
explants were cultured on Murashige and Skoog (MS) media supplemented with
various types and concentrations of hormones. Results indicated that responsive
explants were from stems and cotyledons, based on the formation of shoots. The best
shoot formation was observed on MS medium supplemented with 0.5 mg/L NAA and
1.0 mg/L BAP. The studies also included cellular parameters such as Mitotic Index
(MI), chromosome counts, ploidy level determinationand nuclear DNA content, and
mean cell and nuclear areas. Investigation of the changes that occurred as the plants
were transferred from in vivo to in vitro conditions were also made. The results
showed that the chromosome number in vitro was higher than in vivo. Besides,
changes in MI, ploidy level or nuclear DNA content, mean cell and nuclear areas
were detected which could lead to somaclonal variations. |
