%X Poor exocarp colour development is a common postharvest problem for early harvested ¡°Hass¡± avocado fruit during ripening, which affects fruit quality and consumer preference. Therefore, measures to improve ¡°Hass¡± avocado fruit colour developments are of great importance in the industry. This study investigated the effectiveness of postharvest methyl jasmonate treatment to improve early matured ¡°Hass¡± avocado fruit exocarp colour during ripening. The results showed that T1 (10 ¦̀mol∙L−1) and T2 (100 ¦̀mol∙L−1) MeJA treatment increased visual colour, and decreased objective colour parameters (L*, C* and h˚) during ripening when compared with control fruit. Moreover, MeJA treated ¡°Hass¡± avocado fruits had lower total chlorophyll content and higher total anthocyanin and cyanidin-3-O-glucoside concentration during ripening. In conclusion, ¡°Hass¡± avocado fruit post-harvest treated with either T1 (10 ¦̀mol∙L−1) or T2 (100 ¦̀mol∙L−1) MeJA concentration improved exocarp quality attributes such as colour parameters (L*, C* h˚ and visual colour) and pigments (total anthocyanin and cyanidin-3-O-glucoside) during ripening, therefore, can be recommended for avocado fruit.
