Breaking dormancy of gladiolus corms and inhibitors inducing dormancy

Acta Horticulturae 1974; (43, II): 393-404

Breaking dormancy of gladiolus corms and inhibitors inducing dormancy

Soaking gladiolus corms in a 20 p.p.m. benzyladenine solution for 24 h, followed 3 days later by resoaking in a GA solution at 100 p.p.m., resulted in dormancy breaking and in good shoot and root growth after sprouting. Three groups of inhibitors were present in the ethyl acetate soluble acidic fraction of methanolic extract from corms. These are abscisic acid (ABA), a fatty-acid-like substance and some phenolic compounds.
