PH3 concentrations and durations led to different phytotoxicity levels with the two cultivars (Table 3). Fumigation treatments at 1.83mgL−1 PH3 for 3 d at 5 ◦C had significant negative effects on postharvest quality of ‘Siberia’ and ‘Sorbonne’ lilies.Damageindices of the two cultivars were above 4.0 and flowers were not saleable. There were no significant differences for vase life and damage index of the two cultivars between control and treatments at 1.66mgL−1 PH3 and 12% CO2 for 16 h, and 2.29mgL−1 PH3 for 2 d.
