Tropical fruits cannot be stored at low temperatures due to the chilling injury phenomena. With the goal of reducing the chilling injury, we tested 10 −4 and 10 −5 M of methyl jasmonate (MJ) treatment before the storage of red and white cultivars of guava fruits at 5 °C for up to 15 days plus two da...
