Egeria densareleath释放对其他物种有害的化感物质，包括蓝藻。在自然条件下，E. densa和Microcystis aerodynosaca可在不同光照水平的各种水生系统中发现。E.在M.在不同的光合有效辐射（PAR）强度下，测定了不同光合有效辐射强度下的光合速率。研究了M.在与E.密度。对照实验不加E. densa对M.在相同的条件下，将光合有效辐射强度的作用与化感作用区分开来。E. densaonM.光合有效辐射强度显著影响着大气层温度。PAR强度低于或高于适宜范围进一步抑制M.共存下的航空航天。研究表明，E. densac可用于生物抑制M.在各种光照条件下，光密度（OD）与胞内H_2O_2含量呈强二阶多项式分布。在对照和共存条件下均发现了aerobic。在E.密度化感作用下，OD可作为一种简便的方法来获得M上的近似胁迫状态。铜绿。
Egeria densarelease allelochemicals harmful to other species, including cyanobacteria. Under natural conditions,E. densaandMicrocystis aeruginosacan be found in various aquatic systems with different light levels. The effect that the coexistence ofE. densahas onM. aeruginosawas tested under different photosynthetically active radiation (PAR) intensities. The growth, chlorophyll-a, oxidative stress, and antioxidant activities ofM. aeruginosawere quantified after 7 days of coexistence withE. densa. A control experiment withoutE. densawas conducted forM. aeruginosaunder the same conditions to distinguish the effect of the PAR intensity from the allelopathic effect. The allelopathy ofE. densaonM. aeruginosais significantly influenced by the PAR intensity. PAR intensities lower or higher than the favorable range further suppressedM. aeruginosaunder coexistence. Research has revealed that the allelopathic effect ofE. densacan be utilized to biologically suppressM. aeruginosaunder various light conditions. Strong second-order polynomial distributions between the optical density (OD) and cellular H2O2content ofM. aeruginosawere found for both the control and coexistence conditions. In the practical application ofE. densaallelopathy, OD can be adopted as a convenient method to obtain an approximate stress status onM. aeruginosa.
