Abstract :
Mechanical properties data of Iceberg lettuce leaves are described in relation to the applied
agronomic variables and post-harvest treatment. Leaf tissue strength and stiffness were
both reduced significantly in plants grown with 120 kg/ha applied nitrogen compared with
plants grown with 0 kg/ha applied nitrogen. Leaf tissue strength and stiffness were
increased significantly in plants grown with added calcium at 80 kg/ha. Significant
reductions in stiffness and increases in failure strain were associated with reduced
hydration. These findings show that agronomy changes in mechanical properties are as
large as maturity and post harvest induced turgor changes, which has implications for both
quality and damage of cut salads. C 2005 Springer Science + Business Media, Inc
