Role of exogenous putrescine on the metabolism of conjugated polyamines in mechanically damaged plum during storage.

The role of exogenous putrescine in the reduction of the damage on mechanically damaged plums (Prunus salicina, cv. Black Star) was investigated. Plums were pressure-infiltrated with 1 mM putrescine, mechanically damaged with a compressive force of 50 N, and stored at 10 deg C for 28 days. Firmness, and ethylene and polyamine levels were determined. Fruits treated with putrescine showed significantly reduced deformation under the impact force. Also, putrescine-infiltration improved the texture attributes, including maintenance of significantly higher whole fruit firmness and significantly lower fruit flesh deformation during storage. Lower ethylene emission by treated fruits than by the controls was also observed. Cell-wall-bound putrescine and spermidine accumulated in treated fruits during the first 2 weeks in storage and free spermidine increased in damaged control fruits during the first week in storage.
