An experiment was conducted under greenhouse conditions at Lavras Federal University Lavras, in order to verify the effect of P and Zn rates in the amount of nutrients at the leaves and the stem of acerola fruit tree (Malpiglia glabra L.) seedling. The experimental delineation was in randomized blocks, in a 2 factors design (4x3), with 4 replications per treatment, with 2 plants per plot. The seedlings were submitted to four different rates of P ( 0, 150, 300 and 450mg dm-3 of soil) obtained from Triple superphosphate and three rates of Zn ( 0, 5 and 10 mg dm-3 of soil) obtained from Zinc sulphate. After 100 days, the seedlings were harvested and the quantity of N, P, K, Ca, Mg, S, B, Cu, Zn and Mn in the dry matter of the leaves and stem was evaluated. The interaction of P and Zn presented a significant effect over the amount of Ca, Cu, Fe and Mn at the leaves dry matjer and the other nutrients amount were affected by the P. The Zn affected only the amount of Zn in the stem dry mather. The largest amount of all nutrients at the leaves and the stem was obtained by using 450 mg P dm-3 of soil.
