Abstract:

Abstract : The research of allelopathy have developed from describing phenomenon to expounding mechanism. In the research of mechanism, it is a main approach that utilizes the single allelochemicals as a donor. This paper summarizes the mechanisms of allelopathy of some single allelochemicals, such as phenols, terpenoids and alkaloids. Influence of these allelochemicals on receiver plants refer to inhibition of activityof key enzymes in seed germination and substance metabolism, decrease of photosynthetic rate, damage of cell ultrastructure and the membrane system. We suggest potential future directions in the research of mechanisms of allelopathy is to reveal the physiological processes of allelochemicals action and find out the regularity between the allelochemicals structure and its action target system.
