Methyl jasmonate promotes apple fruit degreening independently of ethylene action.

Climacteric 'Fuji' apples (Malus xdomestica Borkh.) were treated with water, 0.45 mmol(.)m(-3) 1-methylcyclopropene (MCP), 2 mmol(.)L(-1) methyl jasmonate (MJ), or both MCP and MJ. Fruit were kept at 20 degrees C for 17 days after treatment. Ethylene production, respiration, and color change were all inhibited following MCP treatment. Ethylene production following MJ treatment fluctuated below and above that of controls, but was representative of postclimacteric apples at all times. Rates of respiration and color change were enhanced by MJ, even when fruit were previously treated with MCP. The results indicate that MJ can enhance rate of color change and respiration in apple fruit independently of ethylene action.
