Transit vibration is a potential risk that may cause fruit deterioration. Regulating energy metabolism is recognized for attenuating fruit abiotic/abiotic stresses. To explore the role of energy metabolism in the response of fruit to vibration stress, this research investigated the effects of exogenous treatment with adenosine triphosphate (ATP) and 2,4-dinitrophenol (DNP) on fruit after simulated vibration stress. The results demonstrated that DNP treatment induced significant energy depletion, which exacerbated the adverse physiological responses induced by vibration stress. In contrast, ATP regulated higher fruit energy levels and significantly alleviated fruit quality deterioration. This is achieved by supplying direct energy substances, maintaining higher energy charges, inhibiting ethylene biosynthesis, elevating the antioxidant system, and suppressing cell oxidative damage. The results demonstrated the positive role of fruit energy metabolism response to vibration stress. Ensuring sufficient energy level may be a promising strategy for controlling vibration-induced adverse physiological responses and a potential method to maintain fruit quality.
运输振动是一种可能导致果实变质的潜在风险。调节能量代谢被认为可以减轻果实的非生物/生物胁迫。为了探究能量代谢在果实对振动胁迫响应中的作用,本研究调查了用三磷酸腺苷(ATP)和2,4-二硝基苯酚(DNP)进行外源处理对模拟振动胁迫后果实的影响。结果表明,DNP处理导致显著的能量消耗,加剧了振动胁迫诱导的不良生理反应。相比之下,ATP调节了较高的果实能量水平,并显著减轻了果实品质的恶化。这是通过提供直接能量物质、维持较高的能荷、抑制乙烯生物合成、提升抗氧化系统以及抑制细胞氧化损伤来实现的。结果证明了果实能量代谢对振动胁迫响应的积极作用。确保充足的能量水平可能是控制振动诱导的不良生理反应的一种有前景的策略,也是维持果实品质的一种潜在方法。
