Some factors influencing in vitro cultures of potted Hibiscus rosa-sinensis L. using nodal cuttings were investigated. A protocol using a modified MS medium helped to overcome chlorosis, shoot tip necrosis (STN) and leaf drop. These disorders have been caused by mineral imbalance associated with calcium and iron deficiency. STN and leaf drop were overcome(More)
Dwarf genotypes of the economically important flowering potted plant Kalanchoe blossfeldiana were developed by molecular breeding. Root inducing (Ri)-lines were regenerated by applying CPPU to the hairy roots, which were produced by inoculating leaf explants with a wild-type Agrobacterium rhizogenes strain ATCC15834. Amplification by polymerase chain(More)
The Campanula genus comprises several economically important ornamental plants species. Wide hybridisation is a method to increase phenotypic variability, but is limited due to interspecies hybridisation barriers. In this study we investigated whether ovule culture could be used to increase the success rate of interspecific hybridisation between C.(More)
In this paper, we present a method for animating multiphase flow of immiscible fluids using unstructured moving meshes. Our underlying discretization is an unstructured tetrahedral mesh, the deformable simplicial complex (DSC), that moves with the flow in a Lagrangian manner. Mesh optimization operations improve element quality and avoid element inversion.(More)
Interspecific hybridization is a useful tool in ornamental breeding to increase genetic variability and introduce new valuable traits into existing cultivars. The successful formation of interspecific hybrids is frequently limited by the presence of pre- and post-fertilization barriers. In the present study, we investigated the nature of hybridization(More)
Kalanchoë blossfeldiana and its cultivars are important worldwide as potted plants. Their improvement relies mainly on cross-breeding and interspecific hybridization, although the use of the resource of wild species was limited. The present study aimed to characterize novel features of interspecific hybrids that can increase attractiveness of these(More)
Interspecific hybridisation creates new phenotypes within several ornamental plant species including the Campanula genus. We have employed phenotypic and genotypic methods to analyse and evaluate interspecific hybridisation among cultivars of four Campanula species, i.e. C. cochleariifolia, C. isophylla, C. medium and C. formanekiana. Hybrids were analysed(More)
