为了明确桃果实缝合线软化与乙烯的关系,用1-MCP（1-methylcyclopropene）处理生长期的桃果实,用气相色谱测定乙烯的发生,观察缝合线软化果的发生率以及1-MCP对叶片和果实品质的影响。结果表明,1-MCP能有效地降低生长前期桃果实缝合线部位及种仁中乙烯的水平;减少种胚败育,其败育率仅为对照的20%;减少缝合线软化果的比例,软果率仅为2%,而对照则高达23%;1-MCP未对果实品质和叶片产生不良影响。因此认为1-MCP不仅能抑制果实采后贮藏过程中乙烯的发生,而且也能抑制生长期果实中乙烯的发生,可为采前生产上应用提供参考。

In order to know the relationship between suture softening of peach fruit and ethylene,experiment was carried out with 1-MCP（1-methylcyclopropene） treating the peach fruit at growth period,using gas chromatography to determine ethylene level in fruit,observing the rate of fruit suture softening and influence of 1-MCP on leaf and fruit quality.The results showed that,1-MCP could effectively reduce the ethylene levels in suture site and kernel of peach fruit,reduce the embryo abortion with 80% compared with control;reduced suture softening fruit ratio,which was only 2% while the control was high up to 23%;adverse effects of 1-MCP on fruit quality and leaves was not found.1-MCP not only inhibited the ethylene occurs in fruit during postharvest storage,but also inhibited the ethylene occurring in fruit during growth.It can provide reference to 1-MCP applications in pre-harvest production.
