Exacum Styer Group plantlets were regenerated through direct organogenesis from leaf explants. Four genotypes were evaluated on MS media supplemented with combinations of BA (0, 0.44, 2.22, 4.44, or 8.88 μM) and NAA (0, 0.05, 0.54, or 2.69 μM) for direct shoot organogenesis without an intervening callus phase. Regression analyses were used to analyze and interpret the data. There were significant genotype, media, and genotype x media interactions for several variables. Genotypes 01-09-01 and 01-37-61 had the highest number of shoots per explant across media (10.2 and 6.6, respectively) while the 4.44 μM BA plus 0.54 μM NAA treatment induced the greatest number of shoots among the genotypes evaluated.
