Gibberellins (GA) - Gibberellins have been used to promote stem elongation and shoot
production of Alpinia zerumbet (Pers.) B.L. Burtt & Rosemary M. Sm. Stem elongation was
promoted by GA3 applications at 50 mg·L-1 and higher and application rates of 400 and SOO
mg·L-1 increased shoot production (Stamps, unpublished).
