Growth Cycle of Gladiolus

Abstract

Investigation of growth cycle of gladiolus was carried out. The cycle started with germination of the non-dormant corm, resuming its vegetative growth. At the 4 – leaf stage, reproductive growth began with floral initiation at the growing point of the plant. In the mean time, formation of new corm and cormel took place. Spike emergence appeared when the plant reached the 7 – 8 leaf stage. Vegetative growth continued until dying-back of the aerial part, leaving the new corms and cormels dormant until resumption of consecutive cycle.
