Abstract:

This experiment was purposely to research the flowering characteristics of oriental lily bulbs stored at low-temperature (firstly cold storage at 2℃for 74 day, then frozen storage at -1℃ for 135 days). The analysis for flowering characteristics such as flower stem length, numbers of inflorescence, size of the first inflorescence and flowering duration was as followed: For ‘Siberia’ bulbs with perimeter12-14 cm and 14-16 cm, ‘Acapulco’ bulbs with perimeter12-14 cm and 14-16 cm, ‘Sorbonne’ bulbs with perimete12-14 cm and 14-16 cm, the suitable storage period was 74-102 days, 72-87days, 42-87 days, 74 days, 42-87 days and 42-87 days respectively. For ‘Acapulco’ bulbs with perimeter 14-16 cm, the shortest storage period was more than 42 days, and for the other kind of bulb, the shortest storage period was more than 29 days. Moreover, for both ‘Sorbonne’ bulbs with perimeter 12-14 cm and 14-16 cm, the storage period could be delayed to 102-209 days.
