3.6. Changes in the concentrations of total and individual sugars
All NO fumigation treatments significantly (P ≤ 0.05) reduced
concentrations of total sugar in the pulp of fully ripe fruit (1.09-, the pulp of ripe fruit was reduced with all the NO treatments but
the reduction was highest with 20 and 40 L L−1 NO. Four-week
cold-stored fruit fumigated with 40 L L−1 NO had the significantly
highest reduction in fructose concentration (1.52-fold) over the
control.
The concentrations of total sugars, sucrose and fructose in the
pulp of ripe fruit stored for 2 weeks were significantly (P ≤ 0.05)
higher (12.3%, 17.8% and 9.5%, respectively) than in 4-week coldstored
fruit (Table 1). The interaction between NO fumigation and
storage period was found to be significant only for total sugars in ripe fruit following 2 and 4 weeks cold storage (Table 1).
