Water extracts from five kinds of mangrove plants Bruguiera gymnorrhiza, Kandelia candel,Excoecaria agallocha,Cerbera manghas and Acanthus ebracteatus were used to study the allelopathic effects on red-tide algae Phaeocystis globosa and Heterosigma akashiwo by measuring the cell density of treated algae.Besides,impacts of heat treatment on allelochemicals were examined.The results showed that both of dry powder and fresh tissue water extracts had significantly inhibitive effects on the two red-tide algae.On the fifth day,the inhibitive effects of dry powder water extracts on P.globosa and H.akashiwo were in the order of E.agallocha> K.candel> A.ebracteatus> B.gymnorrhiza> C.manghas.Fresh tissue water extracts of B.gymnorrhiza and K.candel had the most inhibitive effects on the two algae.Heat treatment study showed that algaecidal allelochemicals of K.candel and E.agallocha were relatively unstable,but algaecidal allelochemicals of B.gymnorrhiza and A.ebracteatus were relatively stable under high temperature condition.
