Abstract:
Banana as one of the climacteric fruits which is sensitive to postharvest fungal diseases has a short shelf life. Applications of salicylic acid as antimicrobial and anti-ethylene compound and mentha extraction as antimicrobial compound can be effective to increase postharvest life of banana.In order to evaluate the effect of salicylic acid and mentha extraction on some quantitative and qualitative post-harvest traits of banana, an experiment in a completely randomized block design with two factors, salicylic acid in three levels of 0, 2 and 4 (mM) and mentha extraction in four levels of 0, 100, 150, 200 (mg. l) with three replication was performed. Different parameters including the percentage of weight reduction, fungi rot, total soluble solids, reduced sugar, ascorbic acid, starch and quality were measured. The result showed that all of the treatments especially salicylic acid (2 mM) in combined to 150 or 200 (mg. l) of mentha extraction improved the quality of fruit and decreased the lesions of crown and stem end rot compared to control treatment. All of treatments decreased the percentage of weight loss, total soluble solids and reduced sugar but increased ascorbic acid and starch in treated fruits. Thus, it is suggested that 2 mM of salicylic acid together with 150 mg/L of mentha extraction can be used to increase the postharvest life and quality of banana.
