Application of Plant Allelopathy in Controlling of Algal Bloom

Abstract:

With the serious water pollution,the "algal bloom","red tide" formed by the overpopulation of algal is getting worse.At present,different methods including chemical,physical,biological were used to inhibit the growth of algae in polluted water.However,the characteristics of these methods are difficult controlling,high cost,and damaging the ecology.In order to develop a low cost and ecologically safe method to inhibit the growth of algae,plant allelopathy is introduced.In this review,the research progress of algal-inhibition with plant allelopathy was introduced,the types of plant allelopathy and the chemical composition of allelochemicals were summarized,the mechanisms and perspective of plant allelopathy were discussed.
