Abstract: Tea plants (Camellia sinensis, L.) were cultured in nutrient solution from spring to summer to evaluate the role of Al on their growth and absorption of P which was supplied either at a low or high level. The results showed that tea plant growth was controlled by the amount of P as well as the amount of Al. Maximum growth of both roots and shoots occurred with 0.4 mM of Al in the presence of 0.1mM of P and with 1.6mM of Al in the presence of 0.8 mM of P. Also, in the presence of 0.1mM of P, Al stimulated the absorption of P and promoted the growth of the plants. In the presence of 0.8 mM of P, Al alleviated the toxicity of excess P, enhanced the absorption of P and promoted the growth. These results suggest that Al plays a regulatory role in the effective absorption and utilization of P. In addition, although Al caused a considerable decrease in the Ca content and a slight reduction in the Mg content, it increased the absorption of N and K by tea plants.
