    Environmental effects on growth of tissue cultures of a woody solanum species (Solanum laciniatum)
    (1989) Heide Clock
    Tissue culture experiments were conducted with four genotypes of Solanum laciniatum from New Zealand. Environmental effects on the character "callus growth" were studied for two factors (medium type and a temperature-light combination) at each of the four medium types. These studies were applied to all the four genotypes, and their response functions were analysed. On Sommer media the genotype effect interacts completely with the environmental effects. On Murashige and Skoog media the effect of the non-related genotype was consistently distinguishable from the effects of those genotypes descending from self-pollination, i.e. on MS media the genotypic effect can be observed but it is masked on SO medium. This separability of effects is not influenced by the other environmental situations such as hormone concentrations, light or temperature.
