Effects of Gibberellic Acid on Stem Length of Popular Lisianthus Cultivars

Lisianthus is a popular cut flower with problems of insufficient stem length that reduce marketability. Plant growth regulator GA3 was applied at multiple treatment levels and stem length was recorded. Cultivars treated with GA3 showed increased stem length. 250 ppm was most effective for ‘Mariachi White’ and 750 ppm was most effective for ‘Mariachi Pink’.
