Abstract

Ethylene has key roles in triggering and speeding up ripening processes, which in tomatoes take the form of various qualitative changes. Tomatoes, just like all climacteric fruits, need a continuous ethylene exposure to accelerate ripening. Therefore, it is possible to use ripening regulators preventing ethylene binding. According to some studies, chlorophyll fluorescence measurements can be used at least as efficiently as tristimulus colorimetry classifying tomatoes based on maturity. Measurements were carried out by treating fresh tomatoes with 1-MCP (1-methylcyclopropene) at six different stages of ripening and studying the changes in chlorophyll content related quality characteristics (e.g. surface colour, chlorophyll fluorescence) during postharvest storage (two-week refrigerated storage at 15 °C followed by a two-week shelf life). According to our results, chlorophyll content and photosynthetic activity of the treated samples decreased much less than those of untreated ones. Additionally, anti-ripening treatment proved to be more effective on tomatoes at an earlier stage of ripening.

1-MCP 处理对贮藏期间番茄光合叶绿素活性的影响

乙烯在触发和加速番茄成熟过程中起着关键作用，番茄的成熟过程表现为各种质变。西红柿和所有气候性水果一样，需要持续接触乙烯才能加速成熟。因此，可以使用催熟调节剂来防止乙烯结合。一些研究表明，叶绿素荧光测量法至少可以与三基色法一样有效地根据成熟度对西红柿进行分类。测量方法是在西红柿成熟的六个不同阶段用 1-MCP（1-甲基环丙烯）处理新鲜西红柿，并研究叶绿素含量在采后贮藏（15 °C冷藏贮藏两周，然后是两周的货架期）期间与质量特征（如表面颜色、叶绿素荧光）相关的变化。结果表明，处理过的样品叶绿素含量和光合作用活性比未处理过的样品下降得少得多。此外，防成熟处理对成熟期较早的番茄更有效。
