Abstract
The growth periodicity of Allium triquetrum plants grown outdoors was assessed. Simultaneously the effect of temperature on initiation and development of flower buds was investigated. The first inflorescence initiated in mid-October and bloomed in mid-March of the following year. When bulbs were stored at different temperatures from August 2 to October 2, the optimum temperature for flower bud initiation and subsequent differentiation was 15°C. But bulbs stored at 5 and 10°C bloomed earlier. The longer scapes were obtained when bulbs stored at 10°C for 2 months were grown in the greenhouse kept above 10°C. Bulbs stored at 5 or 10°C for 2 months from early August and grown in the greenhouse kept above 10°C produced flowers with longer scape in late December.
