The Effect of Postharvest Methyl Jasmonate Treatment on the Expression of Some Genes of Ethylene Biosynthetic Pathway and Qualitative Properties of Strawberry Fruit

چکیده مقاله

Strawberry (Fragaria× ananassa cv. Sabrosa) fruits, were harvested at commercial ripeness time (> 75% of the surface red color), from a commercial production greenhouse and transported to the postharvest laboratory of Urmia University. Fruits were selected for uniformity in size and ripening, and lack of defects then treated with different concentration of MeJA (0, 10, and 100 μmol/l), and packed in polyethylene boxes to store for 12 days at 3±0.5◦ C and 85–95% RH. Fruit quality parameters and ethylene biosynthetic pathway genes expression rates were measured just after harvest (control) and every 4 days until day 12. In order to treat with MeJA vapor, the fruits were transferred 100× 100× 4 cm3 boxes containing filter papers impregnated with MeJA (Sigma Aldrich) at room temperature (25±1◦ C) for 16 h.
