Enhancement of storage life and maintenance of quality in tomato fruits by preharvest salicylic acid treatment

Tomato fruits are usually characterized by a short postharvest life. Their quality decreases during storage due to losses in nutritional and decay. Salicylic acid (SA) has an important role plant development response environmental stress. This research aimed at evaluating the effects of preharvest salicylic application on extending life, ripening tomatoes ( Solanum lycopersicum cv. Baraka). As hybrid seed, “Baraka” cultivar is appropriate for subtropical regions. Three consecutive weeks before harvest, foliar spraying with SA was applied different concentrations (1, 2, 4 mM). After 10, 20, 30, 40 days 10°C 85–95% relative humidity (RH), had decreased levels a* value (redness), decay, electrolyte leakage, chilling injury after being treated acid. In comparison control, these characteristics were linked increased firmness, titratable acidity, ascorbic acid, ascorbate peroxidase activity. According findings, fruit best maintained mM SA, whereas it least effective 1 SA. Overall, results showed that, can be considered potent treatment that effectively control loss.
