Easter lily plants (Lilium longiflorum Thunb.), derived from tissue culture and grown continuously, were subjected to various photoperiod and chilling treatments. Lilies grown with daylength extended either with high-intensity discharge (HID) or incandescent lights flowered in the same number of days, but had more flower buds with HID lamps. Flowering was delayed and plants produced more leaves as photoperiod was reduced from 16 to 12 hours. The numbers of leaves, primary, secondary, and tertiary flowers, and the time to flower were all significantly reduced as the duration of extended lighting was increased from 0 to 6 weeks. As the number of weeks of cooling at 5°C increased from 0 to 5, time to flower was significantly reduced.
Trials were conducted in California to evaluate techniques to extend post-harvest life of Western shipper-type muskmelon cultivars (Cusumis melo L.). The use of .025 mm polyethylene bags, either as individual melon wraps or as liners for 18 kg commercial cartons, minimized water loss and associated softening of the fruit. A three minute dip in 58-60°C water effectively checked surface mold and decay. The combination of hot water dip and polyethylene carton liner maintained high quality marketable fruit for at least 30 days of cold storage at 2-4°C. This technique would require only modest changes in commercial handling practices, with minimal additional per carton cost. Commercial utilization of this technique could stimulate the export of California muskmelons to Pacific Rim countries.
