Waterlogging stress has two phases like waterlogging phase and post-waterlogging phase where both are injurious to plants. Susceptible plants normally die at post-waterlogging phase due to damaged root system, sudden rexoygenation, dehydration and photoinhibition of the desubmerged tissues. Formation of reactive oxygen species (ROS) is the main result of reoxygenation stress that can cause oxidative damage of the functional tissues responsible for normal physiological activities. There are almost all types of hormones responsible to recover plants from these destructive phenomenons. Among these hormones ethylene and abscisic acid (ABA) are the main regulators to overcome the reoxygenation and drought like stresses in plants at post-waterlogging condition. The balanced crosstalk among the hormones is highly important for the survival of plants at these stresses. So this paper is completely a precise summary of hormonal homeostasis of post-waterlogged plants through physiological, biochemical and signaling pathways.
涝渍胁迫有两个阶段，即淹水阶段和淹水后阶段，这两个阶段对植物都有伤害。易感植物通常在淹水后阶段死亡，原因是根系受损、突然复氧、脱水以及淹水后组织的光抑制。活性氧（ROS）的形成是复氧胁迫的主要结果，它会导致负责正常生理活动的功能组织发生氧化损伤。几乎所有类型的激素都负责使植物从这些破坏现象中恢复过来。其中，乙烯和脱落酸（ABA）是在淹水后条件下克服植物复氧和干旱等胁迫的主要调节因子。激素之间的平衡相互作用对于植物在这些胁迫下的存活至关重要。因此，本文完全是通过生理、生化和信号通路对淹水后植物激素稳态的精确总结。
