Effect of temperature, storage period and bulblet size on growth of hyacinth bulblet ‎‎(Hyacinthus orientalis L.)‎

Hyacinth (Hyacinthus orientalis L.) is one of the most popular ornamental bulbous plants in Iran and the world. Hyacinth bulbs are propagated by daughter bulbs. Storage conditions after harvest of daughter bulbs are important on next growth quality and development rate of them to become as a mother's bulbs. The present study was designed and conducted to investigate the effect of temperature, storage period and also size of daughter bulbs on growth of first generation of daughter bulbs after cultivation in three separate experiments. Results indicated that the highest fresh weight of bulblet (3.70 g) obtained in 3 cm bulblets with 8 weeks storage period at 4°C. Also, in storage at 10°C, the highest fresh weight of bulblet (4.50 g) was observed by interaction between 10 weeks storage period and 3 cm bulblets. The highest fresh weight of bulblet (3.24 g) was obtained in 3 cm bulblets with 10 weeks storage period at 20°C. Finally, results of this study indicated that storage period of the first generation of daughter bulbs can be decreased by reducing the storage temperature.
