Interactive effects between plant allelochemicals, plant allelopathic potential and soil nutrients

Plant allelopathy relates to many ecological factors. The deficit of soil nutrients can influence the production of plant allelochemicals,and thus,influence plant allelopathic potential,while plant allelochemicals can influence the form and level of soil nutrients by the ways of complexation,adsorption,acid dissolution,competition,inhibition,and others. In this paper,the interactive effects between plant allelochemicals,plant allelopathic potential and soil nutrients were summarized,and further research aspects in this field were prospected. It was suggested that following aspects should be strengthened: 1) the integration of plant allelopathy and soil-plant nutrition research to more precisely and deeply interpret the relationships between plant allelochemicals,plant allelopathic potential and soil nutrients,2) the integration of plant allelopathy and ecosystem nutrient cycling research to simulate the plant nutrients disturbance in nature and make the allelopathy research results more true and more reliable,and 3) the allelopathy research with soils containing excessive nutrients or polluted to provide new ideas and scientific basis in revealing the mechanisms of plants interaction and biomass variation in agricultural and forestry production,and in ecological protection.
