The effects of daylength and gibberellic acid on the cormel formation and some growing features in gladioli were investigated, using corms or cormels of four cultivars, i.e. Professor Goudrian, Snow Princess, Valeria and Spotlight. 2. The cormel formation was recognized around and after flowering in the plants developed from mother corms, while new cormels had been already formed before the flower bud differentiation in the plants from mother cormels. 3. A short day condition around and after flowering was favourable for the cormel formation in the plants developed from mother cormels as well as in those form mother corms. 4. Foliar application of gibberellic acid just after the emergence of inflorescences promoted the cormel formation under the natural photoperiod from late summer to early autumn in both plants developed from mother corms and cormels. 5. A great diversity was noticed among cultivars used on the short day requirement for the cormel formation., Bulletin of the University of Osaka Prefecture. Ser.
