Treatments with gas compositions applied to cut flowers of Narcissus tazetta ‘Shahla’ for six days of cold storage (2 ± 1 °C)
| Treatment | Explanation |
|---|---|
| MAP1 | passive-MAP (0.03% CO2 and 21% O2) |
| MAP2 | vacuum packaging (VP) (0.0% CO2 and 1% O2) |
| MAP3 | high carbon dioxide + air oxygen (40% CO2 and 21% O2) |
| MAP4 | high carbon dioxide + low oxygen (20% CO2 and 10% O2) |
| MAP5 | high carbon dioxide + high oxygen (40% CO2 and 40% O2) |
| MAP6 | air carbon dioxide + high oxygen (0.03% CO2 and 40% O2) |
