| 研究发现幼果期CAT、SOD、G-POD和AsA-POD活性较高，随着果实的发育进程其活性不断下降，其原因可能是果实发育成熟后期随着膜透性的增大，细胞器被破坏而使活性氧大量积累，超出了机体正常的清除能力，抗氧化酶活性的下降可能是一种植物细胞自我调节机制。
在抗氧化物质的积累中，TF、TP和GSH的积累趋于显著相关，与PPO表现出了高的相关性(r=0.934，p﹤0.01；r=0.900，p﹤0.01；r=0.901，p﹤0.01)，说明在其积累过程中与PPO有较大关联，诸多研究表明PPO与水果、作物的褐变、提高植物的抗性、酚类物质的合成等生理功能有关。AsA的积累过程比较复杂，在果实发育前期（7月30日）出现一次高峰，之后出现短暂降低后又开始上升，并在10月底出现二次峰值，通过分析其含量与代谢相关酶AsA-POD和DHAR的关系后发现，相关性未达到显著性，由此可以推测，AsA合成与积累更多在于果实自身的合成调控以及外界因素（温度、湿度以及光照等）干扰。
