Continuous aeration affects the growth and nitrogen metabolism of different rice types. It was found that under aeration, chlorophyll content decreased in all genotypes, while root length and oxidation intensity increased. Nitrogen accumulation decreased in some genotypes, leading to changes in enzyme activity related to nitrogen metabolism. Overall, continuous aeration can impact root surface area and oxidation intensity, reduce chlorophyll content, and alter enzyme activity in leaves, affecting nitrogen absorption and plant growth differently in various rice genotypes.
