植物在正常情况下,体内活性氧产生与清除处于平衡状态,不会导致细胞伤害[1]。但逆境胁迫会促进活性氧产生,严重时导致植物伤害或死亡[2]。因此,植物体内的活性氧清除剂的含量或活力水平的高低对植物的逆境能力具有十分重要的意义。超氧化物歧化酶(SOD)、过氧化氢酶(CAT)等是植
Under normal conditions, plants produce and remove reactive oxygen species in an equilibrium state without causing cell damage [1]. However, stress will promote the production of reactive oxygen species, in severe cases lead to plant damage or death [2]. Therefore, the content of active oxygen scavenger or the level of vitality in plants is of great significance to plant adversity. Superoxide dismutase (SOD), catalase (CAT) is a plant
