MCP could inhibit the respiration of climacteric fruits such as Starking and Fuji apple and Feicheng peach in different degree, and this effect was not be able to convert by exogenous ethylene. On the contrary, the effect of 1-MCP on the non-climacteric fruit was not ascertainment: 1-MCP inhibited the respiration of strawberry stored at 20℃ during the whole storage time, while when stored at 0℃, 1-MCP didn't inhibit the strawberry respiration.

1-MCP能够不同程度的抑制跃变型果实富士、红星苹果和肥城桃的呼吸作用，而且这种作用可以不为外源乙烯所拮抗，但对非跃变型果实草莓的呼吸作用的效果则不确定：1-MCP抑制了20℃下草莓的呼吸速率，但并没有抑制0℃下贮藏草莓的呼吸作用。

Starking were used tostudy the effects of 1-MCP on ethylene synthesis metabolism, antioxidant enzyme activity,softening and qualities in different fruits and its regulation mechanism. StrawberryFragariaananassa cv.

Starking苹果为主要试材，研究了 1-MCP 对不同品种/树种的果实中乙烯合成代谢、抗氧化酶活性、果实软化和果实品质的效应及其机制，同时对 1-MCP 在草莓Fragaria ananassa c.v。

MCP could effectively delay the softening of climacteric fruit, such as Starking and Fuji apples and Feicheng peach, but as different fruits had different softening mechanism, the mechanism of 1-MCP inhibiting different fruit softening was different: in Starking apples, the key enzyme to the softening is endo-and exo-PG, while during Feicheng peach fruit softening, the key enzyme was EGase before the 20th d and endo-PG after 20th d during storage at 0℃. 1-MCP inhibited fruit softening mainly by inhibiting PG activity in Starking apple while in Feicheng peach, by inhibiting the activity of EGase in the earlier storage time and endo-PG in the latter time. It was also found that LOX accelerated the initiation of the softening and was regulated by ethylene and 1-MCP in apple and peach.

2.1-MCP能较好的延缓红星、富士和肥城桃等跃变型果实硬度的下降，但是不同品种/树种的果实软化机理不同，1-MCP抑制其软化的机理也不一致：在红星果实中，对软化起主要作用的酶一直为内切和外切两种PG，而在肥城桃软化过程中，前20d以纤维素酶活性起主要作用，20d后软化以内切PG为主。1-MCP主要通过抑制红星果实中PG酶活性来抑制果实硬度的下降；在肥城桃果实中，1-MCP通过抑制前期纤维素酶和后期内切PG活性，延缓了果实硬度的下降。
