The packaging of flowering Phalaenopsis sp. orchids in sealed plastic film offers potential advantages of extending shelflife and maintaining quality by slowing respiration and protection from the hazards of retail distribution. Following treatments, 2-year-old plants, each with three to nine open florets, were stored at 21 to 27C for 76 days under natural light and natural daylengths. Plants were sealed individually in bags of air, or in bags of initially 15% O2, 23% CO2, balance N,, or 20% O2 and 30% CO2. Control plants were left in open air and were watered twice weekly; plants in sealed bags were not watered. Gas concentrations in the sealed bags were monitored twice weekly. The various atmospheres had no effect on floret life. Two distinct patterns of O2 and CO2 variation with time were observed, but inflorescence half-life values were not related to these patterns. Florets on plants in bags had a greater incidence of discoloration.
