Abstract: | Growth responses of a tomato cultivar Ailsa Craig and the ah-, aw- and bls-isogenic/near isogenic lines (IL/NIL) from it were evaluated and compared at cotyledons stage under salt treatment in vivo and in vitro experiments. No differences in hypocotyl and root growth responses were detected between the anthocyanin-containing and the anthocyaninless lines within the in vivo experiments. The anthocyaninless mutants, (except in some cases the bls mutant), exhibited higher callogenic and shoot-forming capacity on both, control and salinized media. It was concluded that for this reason it would be difficult to determine the relationship between the in vivo and in vitro responses of the lines studied and as well as to evaluate the usefulness of the in vitro method in testing these lines for salt tolerance. |
