Variations in ascorbic acid content were large, with differences among the cultivars
greater than between ripe fruit harvested as mature-
green or red-ripe.
The ascorbic acid content
of fruit harvested mature-green and ripened with
the aid of C2H4 was higher than for untreated
fruit. However, this effect was not consistent
among fruit from different growers or fruit harvested
at different times of the year.
