有广泛的共识，在洪水期间监测植物响应的意义时，评估具体的耐受性。然而，一旦水退，植物恢复往往被忽视。本说明强调了在恢复阶段登记电厂运行情况的重要性。两种相反类型的植物生长反应，在洪水期间和之后，进行了讨论。它表明，在洪水期间明显表现不佳不一定涉及降低耐受性，因为植物可以优先节省能量和碳水化合物，以便在恢复期间恢复旺盛的生长。相反，在洪水期间保持植物的正生长可能意味着储量的大量耗尽，从而限制了未来的植物生长。因此，为了准确地估计对这种胁迫的真实的耐受性，应该在淹水和恢复期间评估植物性能。
There is wide consensus about the significance of monitoring plant responses during flooding when evaluating specific tolerance. Nonetheless, plant recovery once water recedes has often been overlooked. This note highlights the importance of registering plant performance during a recovery phase. Two opposite types of plant growth responses, during and after flooding, are discussed. It is shown that an apparently poor performance during flooding does not necessarily involve a reduced tolerance, as plants can prioritize saving energy and carbohydrates for later resumption of vigorous growth during recovery. Conversely, maintenance of positive plant growth during flooding can imply extensive depletion of reserves, consequently constraining future plant growth. Therefore, to accurately estimate real tolerance to this stress, plant performance should be appraised during both flooding and recovery periods.
