| Resumo: |
One of the greatest problems in the elaboration of forestation programs using native species is the lack ofknowledge about seedling production. This study aimed to evaluate the growth ofBauhinÚJfoif=ta seedlings submitted to phosphorus leveis. Elevenday- old seedlings were transplanted to small tubettes (110 crrr') with pinus bark and vermiculite substratum base. The experiment was conducted in an entirely randomized delineation, with six P treatrnents: TO-control (substratum without P addition), Tl-50, T2- 100, T3-150, T4-200 and T5-250 mg drn", with five replications and 20 seedlings per replication, Mter 60 days, the seedlings presented a 98.2% survival rate and good root formation. The height varied in function ofP leveis, with maximum production up to the P dose of 250 mg drn "; 60 days after the transplant, similar behavior for leaf area and dry matter production was observed. Furthermore, the P incorporation increased the phosphorus (P), potassiurn (K) and nitrogen (N) accumulation in vegetable tissues. Seedling growth was positively influenced by P leveIs, and the maximum growth occurred up to the P dose of 250 mg drn". In conclusion, this characteristic showed that the species requires high leveIs ofP during initial growth, under the tubette system.
