| Abstract: | Phosphorus is one of the three essential macronutrients of plant and there are a series of adaptable changes in crops because of the phosphorus deficiency in soil.Large amounts of organic acids are released into the rhizosphere by the roots of many plants and low molecular weight organic acids and its own organic anions play an important role in improving plants' phosphorus nutrition.In order to systematize the roots' micromorphology of plant,in the article the studies on the exudation of low molecular weight organic acids of phosphorus-deficient plants(including sources,composition,kinds and secretion mechanisms),action mechanism and the research methods of organic acids were summarized. |
