The effect of a larger range of NO concentrations
from 1 to 4000 ml l−1 was subsequently
examined. The beneficial effect of fumigation with
1 and 5 ml l−1 NO was confirmed with a 60%
increase in postharvest life being achieved with 5
ml l−1 NO at both 20 and 5°C (PB0.01) (Table
2). However, at higher NO concentrations the
extension in postharvest life was not as great.
