Abstract
The organogenetic capacity of five dwarf mutant strains of Arabidopsis thaliana (L.) Heynh. was generally low as compared with normal line Estland on the B5 media supplemented with 9 different combinations of NAA and BA. Mutant F produced shoots in similar frequency to normal line, but produced roots less frequently. Mutant t and St1 produced shoots at one or two combinations of NAA and BA, but no rootformation was observed at any combination. Mutant le and g produced roots at one or two combinations, but no shoot-formation was observed at any combination. The media combined with NAA at 0.1-1mg/l and BA at 0.1-0.3mg/l were available for regeneration of whole plant in normal line. However, whole plant was scarcely regenerated in the tested dwarf mutants at any combination of NAA and BA.
