In this study the effects of reflective mulches on postharvest fruit quality of ‘Malas Shahreza’ pomegranate was investigated. The experiment was set up in completely randomized block design with various colors of reflective mulches, including silver, yellow and white and four replications. Reflective mulches was spread 43 days before the harvest. After the harvest, fruits was be sampled at weeks 1, 2, 3 and 4 and anthocyanin, ascorbic acid, total soluble solids, total acid, phenolic compounds, and color indexes and antioxidant activity was eva‎luated. The results showed that silver reflective mulch increased anthocyanin content of peel and juice, phenolic compounds, total soluble solids and carbohydrate contents of fruits but has not significant effect on ascorbic acid content of fruit juice compared to plants cultivated in unmulched soil. At the time of storage, silver mulch showed higher postharvest quality than control. Also the colorimetric result showed that although, all applied reflective mulches of silver, yellow and white continued to be effective in increasing fruit red color, in line with previous results silver reflective mulch treatment was numerically superior to others, increased the red color and a* index
