Abstract
The effects of various duration of precooling followed by a long term storage at freezing temperature on flowering of Asiatic Hybrid lily cultivars were studied. Bulbs of cultivars, which had not initiated flower buds and those which had begun to initiate were used to determine the effects of precooling, freezing, and planting dates of the bulbs.1. When bulbs were precooled at 1°C under moist conditions for 46 weeks followed by storage at -2°C, high flowering percentage and an abundance of cut flowers with good quality were obtained whether floral initiation had taken place or not.2. Precooling at 1°C improved flower quality compared with those kept at 5°C or 9°C. Long term storage at -4°C resulted in good flower quality but it delayed sprouting and thus flowering time. Planting fozen bulbs during the hot summer season reduced their flowering potential and flower quality and so it is not recommended.
