In the study, embryo bud of Impatiens balsamina L was cultured on hormone-free MS medium for promoting, MS medium with 6-BA 3 mg/L+NAA 0.5 mg/L for shoot and root formation, and MS medium containing 6-BA 3 mg/L+NAA 0.5 mg/L for flowering respectively. During about 60 days, plant regeneration and flowering of Impatiens baisamina L was finished in vitro.
