Three percent CaCN_2, 1% KCN, 100% N_2 promoted sprouting from dormant corms in summer-flowering gladiolus 'Traveler'. One percent C_2H_4 also promoted sprouting from corms with 30 day cold storage. Hot water and hulling treatments were also effective for promotion of sprouting. However, effect of any treatment was not so great as shown in corms of spring-flowering gladiolus.
