The effect of flooding on the growth parameters and hormonal dynamics (auxins, abscisic acid, cytokinins, gibberellins, and ethylene) has been studied in a vegetation experiment on the leaves of wheat (Triticum aestivum L.) and oat (Avena sativa L.). Growth inhibition during flooding in both species was due to the accumulation of abscisic acid and ethylene, while the repair processes were due to the increased level of auxins, cytokinins, and gibberellins. The difference in the hormonal response in wheat and oat to flooding, in particular, the degree and timing of accumulation of abscisic and indoleacetic acids and different dynamics of the level of cytokinins and gibberellins, induced their different physiological response, which determined the level of their resistance. The growth control of cereals during flooding as well as the hormonal dynamics are proposed to rely on the strategy of plant ontogenetic adaptation.
在一项针对小麦（Triticum aestivum L.）和燕麦（Avena sativa L.）叶片的植被实验中，研究了水淹对生长参数和激素动态（生长素、脱落酸、细胞分裂素、赤霉素和乙烯）的影响。两种植物在水淹期间的生长抑制是由于脱落酸和乙烯的积累，而修复过程则归因于生长素、细胞分裂素和赤霉素水平的增加。小麦和燕麦对水淹的激素反应差异，特别是脱落酸和吲哚乙酸积累的程度和时间以及细胞分裂素和赤霉素水平的不同动态，导致了它们不同的生理反应，这决定了它们的抗性水平。水淹期间谷类作物的生长控制以及激素动态被认为依赖于植物个体发育适应策略。
