On the development of flower bud and corm in gladiolus

Abstract

1. In kunder'd White variety, the inflorescence primordia were formed in the begining of May, when they were planted in the end of March or the middle of April.
2. The primordial flower spike were formed at the time, as soon as the 2 nd normal leaf appeared or just before it.
3. About one month later from the flower bud differentiation, the pollen and ovule formations began, and a few of the top flower buds on a spike stopped their growth after ten days, while the others were developing to be ready. for flowering 9 days after.
4. The flower buds no more developed at the various stages before the pollen and ovule formations.
5. The new corms were growing rapidly as soon as the flowers faded, and their growths continued until the end of September or-the begining of October.
6. The corms from axial bud awaked their growth later than the center did, and the growth of the former continued growing to the middle of October.
7. The cormel growth started rapidly as soon as the flower faded and continued its growth until Nobember.
