Extracellular ATP (eATP) as an essential biological substance can trigger a series of physiological activities in postharvest fruit and vegetable during storage. We performed a systematic meta-analysis to elucidate better the multiple roles of exogenous ATP on the quality maintenance of postharvest fruit and vegetable during storage using a standard mean difference (SMD) with a 95% confidence interval (CI) and a random-effects model. This study determined 25 major indices of physiological activities of postharvest fruit and vegetable according to inclusion criteria. In forest plots, ATP application retarded the senescence (SMD −3.69, 95% CI [−5.32, −2.06]; I2 =100%; p = 0), maintained the nutritive quality (SMD 3.78, 95% CI [1.96, −5.63]; I2 = 100%; p = 0), contributed to high energy charge (SMD 1.99, 95% CI [−0.67, 4.66]; I2 = 100%; p = 0), attenuated membrane oxidant damage (SMD −4.08, 95% CI [−5.98, −2.18]; I2 = 100%; p = 0), and enhanced the antioxidant capacity (SMD 4.37, 95% CI [2.58, 6.15]; I2 = 100%; p = 0) of postharvest fruit and vegetable during storage. In conclusion, the results shed insights into the positive role of exogenous ATP in maintaining the quality of postharvest fruit and vegetable during storage via these physiological activities.
