Phosphorus is an important element that controls the process of plant life, especially during its growth phase. Low\|phosphorus in the soil usually leads to adaptive changes in plants. Yunnan Plateau, being its distribution range, Pinus yunnanensis Franch. reflects great capability of adapting to low\|phosphorus red soil. Therefore, to study the effect of different phosphorus on Pinus yunnanensis Franch. seedlings becomes an important reason to help unveil mechanism of adaptation towards low\|phosphorus. Present study was to analyze growth and internal P content of seedlings (Pinus yunnanensis Franch.) to various phosphorus supplies. The seeds used to culture seedlings were collected from healthy and mature forest of Pinus yunnanensis Franch in Xiushang Forest Park, Tonghai county, Yunnan province, China. The results of test were as follows: (1) The growth of Pinus yunnanensis Franch. seedlings including shoot height（F=2.352，P=0067）, taproot length（F=1.775，P=0.151）, shoot biomass（F=1.359，P=0.269）, root biomass（F=2.807，P=0035） and total biomass（F=1.017，P=0.427） did not present substantial differences between different phosphorus supplies; (2) The range of seedling root/shoot ratio was KH2PO4>Ca3(PO4)2>AlPO4>CK>FePO4.4H2O and that of internal P content was KH2PO4>FePO4.4H2O>AlPO4>Ca3(PO4)2>CK; (3) KH2PO4 was better used by Pinus yunnanensis Franch. seedlings; (4) The internal P content of root was always higher than that of shoot.
