اثر پوترسین و 1- متیل سیکلوپروپان بر خواص کیفی و عمر انبارمانی میوه توت‌فرنگی رقم "سلوا" (Fragaria ananassa Cv. Selva)

Ethylene is an important contributor to the acceleration of fruit ripening and postharvest losses of fruit. Thus, anti ethylene substances could increase storage life of fruits. Thus the effects of 0 (control), 0.5, 0.75 and 1 µL L-1 of 1-MCP and putrescine with 0 (control), 0.5, 1 and 1.5 mM on the storage life (1°C) during 21 day in strawberry fruit Cv. Selva were studied and appearance and the physicochemical characteristics of fruits were measured. A factorial experiment through complete randomized design (CRD) was used. The highest marketability, firmness, citric acid (TA), total soluble solids (TSS), vitamin C and the lowest amount of appearance decay, pH and the ratio of TSS/TA were observed in the treatment of 0.75 and 1 µL L-1 of 1-MCP and 1 and 1.5 mM of putrescine. The results obtained from the experiment showed a positive effect of 1-MCP and putrescine on the storage life of strawberry. The results further showed that the use of 1-MCP and putrescine can act as an effective strategy in postharvest technology of strawberry fruit.
