Spadona	2017	8	.pdf	application/pdf	3577	225	66	Moreover, the storage life and marketability of putrescine treated fruits were prolonged by decreas- ing decay incidence. It is suggested that polyamines maintain fruit firmness by their cross-linkage to the pectin substances carboxyl groups in the cell wall and lead to strengthening of cell wall and consequently decreasing cell wall degrading enzymes activities of pectin methyl esterase (PME), pectin esterase (PE) and polygalactouronase (PG) (Valero et al., 2002).	cache/ahs-3078.pdf	txt/ahs-3078.txt
