摘要：

The effects of 1-methylcylopropene (1-MCP) and storage temperature on the transcription of key mevalonate pathway enzyme genes in relation to alpha-farnesene and the conjugated trienols of apples (cv. White Winter Pearmain) were studied. Fruit samples were treated with 0.7 M 1-MCP and stored at 0 degrees C along with a control fruit were stored at 0 degrees C (Control@0 degrees C) and another group stored at 5 degrees C (Temp@5 degrees C) for 113 d. Results indicated that Temp@5 degrees C improved the alpha-farnesene and CTols content, ethylene production rate, and fruit scald compared with Control@0 degrees C, and 1-MCP@0 degrees C was significantly lower than Control@0 degrees C during storage. Flesh firmness and soluble solid contents of fruit remained unchanged by either treatment in the later period of storage. In response to 1-MCP treatment and storage temperature, qRT-PCR analysis revealed changes in the transcript level of the alpha-farnesene-related genes (HMGR family genes, MdMVK, MdFPPS, and MdAFS) during storage. Thus, the results of this study indicated that 1-MCP treatment and storage temperature could facilitate fruit storage by decreasing the expression of alpha-farnesene-related genes.
