：Vegetative propagated 10-month-old tea [Camellia sinensis (L.) O. Kuntze cv. Huangguanyin] plants grown in pots containing sand were fertilized three times weekly for 17 weeks with nutrient solution at a phosphorus (P) concentration of 0, 40, 80, 160, 400 or 1 000 μmol/L. As P supply increased, root P content increased linearly, while stem and leaf P content increased in a curve shape. Over the range of P supply, the sequence of P content in the three organs is root P content > leaf P content > stem P content, especially in high P-treated plants. P deficiency decreased the P contents in roots, stems and leaves, but had little effects on the Ca content of roots, stems and leaves. P deficiency decreased root Mg content and increased stem Mg content, but showed insignificant effects on leaf Mg content. Leaves from P-deficient (0 μmol/L P) plants had slightly higher C content, lower N content and higher C/N ratio, whereas P supply had little effects on the contents of C and N and the ratio of C to N in roots and stems. In conclusion, P deficiency not only affects contents of nutrient elements in tea roots, stems and leaves, but also altered distribution of nutrient elements among roots, stems and leaves.
