Many studies have attempted to find measures for control of cyanobacterial harmful algal blooms (cyanoHABs) caused by Microcystis, Anabaena, and other bloom-forming plankton species. We have investigated allelopathic inhibition of the submerged macrophyte Myriophyllum spicatum on four phytoplankton species of two taxonomic groups: Chlorophyta Selenastrum capricornutum, Scenedesmus obliquus, and cyanobacteria Microcystis aeruginosa (different strains for toxic, non-toxic, the North Han River originated (NHR) and colonies) and Anabaena circinalis. Inhibitions of unicellular cyanobacteria M. aeruginosa were over 50% for three consecutive days from the 3rd to the 5th day of the coexistence. M. spicatum even inhibited M. aeruginosa at a high initial concentration (1.1 mg L⁻¹ Chl-a). Moreover, M. aeruginosa in a mixture of four phytoplankton species (S. capricornutum, S. obliquus, M. aeruginosa and A. circinalis) was selectively inhibited by M. spicatum. The inhibition of toxic, non-toxic, and NHR of Microcystis by M. spicatum were not significantly different. Colonial cyanobacteria strains were mostly not inhibited by M. spicatum.

许多研究试图找到控制由微囊藻、鱼腥藻和其他形成藻华的浮游生物物种引起的蓝藻有害藻华 (cyanoHABs) 的措施。我们已经研究了沉水大型植物Myriophyllum spicatum对两个分类群的四种浮游植物物种的化感抑制作用：Chlorophyta Selenastrum capricornutum、Scenedesmusobliquus和蓝藻Microcystis aeruginosa（有毒、无毒、北汉江和北汉江起源的不同菌株）菌落）和Anabaena circinalis。抑制单细胞蓝细菌M. aeruginosa从共存的第3天到第5天，连续三天都在50%以上。M. spicatum甚至以高初始浓度（1.1 mg L ^-1 Chl- a）抑制铜绿假单胞菌。此外，M . spicatum选择性抑制四种浮游植物物种（S. capricornutum、S.obliquus、M. aeruginosa和A. circinalis）的混合物中的M. aeruginosa。有毒的，无毒，和NHR的抑制微囊由M.藻没有显著不同。菌落蓝藻菌株大多不受M. spicatum。
