Studies were carried out to investigate whether the shorter shelf life reported for cucumbers with a prolonged period of fruit development on the plant was related to a higher level of ACC (1-aminocyclopropane-1-carboxylic acid). ACC levels were determined in 50 cucumber fruits, cv. Farona, of varying size (11-383 g) and varying age (8-42 days). Fruit age was found to have less influence than fruit size on the level of ACC in fruits at harvest. Small fruits, up to 100 g FW, contained a significantly higher level of ACC than larger fruits. No significant difference between fruits of different age was found but there was a tendency towards a lower level of ACC in older fruits. DM content decreased with increasing fruit size (from 4.3% in fruits less than or equal to 100 g to 3.1% in fruits of 300-400 g) but the decrease was not large enough to account for the lower levels of ACC found in larger fruits. The results do not indicate that the shorter shelf life of cucumbers with prolonged development

on the plant is related to higher levels of ACC in these fruits.
