Allelopathic Effect of Typha Angustifolia L. on Phytoplankton
To pursue an effective method to control phytoplankton blooms, the allelochemicals of Typha angustifolia L. were purified and identified and their allelopathic effects were studied in phytoplankton assemblage assays. We found that the Typha angustifolia L. allelochemicals included 3 phenic acids (o-hydroxycinnamic acid, syringic acid and isoferulic acid, which inhibited the growth of phytoplankton assemblage and the o-hydroxycinnamic acid proved most potent. The combined activity of these phenic acids exerted synergistic inhibitory effects on the growth of phytoplankton assemblage. The results suggested that Typha angustifolia L. and its allelochemicals may control the phytoplankton blooms in eutrophic waters.
