Growth Cycle of Brisbane Lily (<I>Eurycles amboinensis</I> Lindl.)

Abstract

Investigation of the growth cycle of Brisbane lily was carried out. The growth cycle started with emergence of the floral bud in April and the inflorescence continued its growth until May. Vegetative growth began right after blooming. The plant sheded the leaves in November and the bulb consecutively entered the dormant period until March. Floral initiation was found to take place at the growing point of the new bulb as early as the period of dying-back of the leaves. Floral development carried on during the whole period of bulb dormancy and the young inflorescence emerged and bloomed at the early stage of the new cycle of growth.
