%X Phosphorus defficiency,which seriously limits yields and distribution of crops,is a problem extensively existing in soils around the globe.The tendency of P-defficiency will be aggravated by both the ever increasing requirements for grains and energy crisis caused by population explosion in the world.Therefore,how to improve the efficiency of P-fertilizer and to mobilize the P absorbed and fixed in soil through developing the potentialities existing in plants will play an important role in improving grain yields,reducing production costs and protecting eco-environment.In this paper possibility of enhancing the bioefficiency of P is discussed and mechanisms and genetic studies of the differences in P nutrient characteristics of plants are also reviewed for the pourpose of providing theoretical basis for breeding new varieties which can efficiently utilize P fertilizer and tolerate P-defficiency.
