All the treatments showed a beneficial effect on physical, biochemical and sensory parameter of fruits in comparison to control fruits. Among all treatments, 1250 ppb 1-MCP was proved to be the best in retaining the storage quality of fruits under ambient storage. After applying 1-Methylcyclopropene (1-MCP), Aloe vera leaf extracts alone and in combination with CaCl2 and Starlight waxing treatments, fruits were stored under ambient conditions for 45 days, respectively. These treatments in general, slowed down the physiological changes and respiration rate of fruits, thereby proving to be effective in maintaining fruit quality during ambient storage. 1-MCP (1250 ppb) was the most effective treatment in this regard as the fruits retained maximum firmness, titratable acidity and exhibited lower decreases in physiological loss in weight, starch disappearance besides showing lower changes in TSS and sugar contents. Starlight waxing (75%) and Aloe vera leaf extracts, especially in combination with 1 per cent CaCl2 were also quite effective in retaining quality of fruits in comparison to control fruits. These fruits also had higher sensory evaluation rating and hence the best overall acceptability ratings. However, Aloe vera whole leaf extract in combination with 1.0 per cent CaCl2 efficiently reduced spoilage of fruit due to rots during storage. | Effect of some postharvest treatments on storage quality of apple cv. royal delicious under ambient storage
