Effects of postharvest methyl jasmonate (MeJA) treatment on the contents of ascorbic acid and carotenoids, as well as the compositions and contents of volatile organic compounds (VOCs) in cherry tomato fruits were investigated during 11 days of storage at room temperature (25 °C). The results showed that MeJA treatment significantly increased the contents of ascorbic acid and carotenoids, especially lycopene in postharvest cherry tomato fruits. Moreover, MeJA treatment improved the contents of carotenoids derived VOCs such as 6-methyl-5-hepten-2-one (MHO), while had no effect on firmness, sugars and titratable acidity. All above results suggested that the exogenous MeJA application is potential in enhancement of main health-promoting components and VOCs in postharvest cherry tomato fruits.
研究了采后茉莉酸甲酯（MeJA）处理对樱桃番茄果实中抗坏血酸和类胡萝卜素含量，以及挥发性有机化合物（VOC）组成和含量的影响，在室温（25°C）下贮藏 11 天。结果表明，MeJA 处理显著增加了采后樱桃番茄果实中抗坏血酸和类胡萝卜素的含量，特别是番茄红素。此外，MeJA 处理提高了衍生类胡萝卜素 VOC 的含量，如 6-甲基-5-庚烯-2-酮（MHO），而对硬度、糖和可滴定酸度没有影响。所有这些结果表明，外源 MeJA 的应用有可能提高采后樱桃番茄果实中的主要保健成分和 VOC。
