Objective evaluation of firmness in cucumbers and its physiological implications.

A method for evaluating the firmness of cucumber (cv. Muhasan) fruits was developed. fruits were packed in perforated or not perforated polyethylene films, or left unpacked. Other fruits were dipped in water for 1 or 7 h and then kept in non-perforated polyethylene packages. Mechanical properties were evaluated either by a bending test or penetrometer after 24 h of storage. In another trial, fruits were kept at 85-90% relative humidity and 11 or 17 deg C for 1 week, and mechanical properties were evaluated during this period. The elastic modulus of cucumbers during the first day of storage was determined by changes in fruit weight, which depended on water loss or uptake. At 17 deg C and 85-90% relative humidity, the correlation between elasticity and weight was valid only on the first 2 days of storage, and fruits toughened in spite of continuing water loss. Further toughening of fruits could be related to the strength of its cell walls.
