Internodal segments of Torenia fournieri Lind. were cultured on various media to investigate chemical factors influencing in vitro flowering. The elimination or dilution of ammonium nitrate from Murashige and Skoog's medium increased the formation of adventitious buds which subsequently differentiated floral buds. The dilution of mineral salts in Murashige and Skoog's medium enhanced adventitious bud formation, but did not influence the ratio of cultures with floral buds to those with adventitious buds. Among various media tested, in vitro floral bud formation and development of Torenia was best on a medium having 1/5 of the mineral salts and no NH_4NO_3. Eighty-seven percent of the cultures produced floral buds on this medium. Using this medium, the effects of various sugars were also examined. Increasing the concentration of sucrose in the medium (up to 60 g/liter) increased the rate of cultures with floral buds, and stimulated the development of floral buds led to anthesis.
