| Abstract:
Polyamines play an important role in fruit development and have been considered as antisenescence agents. Also, increases in polyamine contents, in response to several stresses have been reported (Valero et al., 1999). This paper describes the role of exogenous putrescine in the reduction of the damage on mechanically damaged plums. Also, the possible role of conjugated polyamines (soluble-conjugated and cell-wall bound) in the maintenance of higher firmness is discussed. | |
