Abstract
The present study aimed to determine the effect of postharvest salicylic acid (SA) treatments on storability and biochemical quality of Bartlett pear fruits at ambient storage conditions. Freshly harvested fruits were treated with salicylic acid solution at 0 (control), 0.5, 1 or 2 mM and fruits were stored at ambient conditions (room temperature) for 21 days storage studies. Data on physiological loss in weight (PLW), fruit spoilage and biochemical quality of fruits (total soluble soils, titratable acidity, ascorbic acid, reducing and total sugars) were recorded. Results revealed that the salicylic acid treatments significantly minimized the PLW and fruit spoilage. At 21 days of storage at ambient conditions, the lowest PLW (13.76 %) and fruit spoilage (21.70 %) was noted with SA at 2 mM. All three SA treatments effectively retained the biochemical attributes of fruits i.e. total soluble soils, titratable acidity, ascorbic acid, reducing and total sugars as compared to control fruits. In conclusion, Salicylic acid at 2 mM treatment to the Bartlett pear fruits after harvest can be useful in minimizing the PLW and fruit spoilage and also maintaining the biochemical quality of fruits during ambient storage conditions.
