ABSTRACT

Melanoxylon brauna is a tree species native to the Atlantic Forest of high ecological and economic
value. The objective of this study was to evaluate the growth and nutritional status of seedlings of
two Melanoxylon brauna cultivars grown in substrate with different controlled-release fertilizer
doses (CRF). The experiment was arranged in a randomized block 4 × 2 factorial design, with
four CRF doses (0, 2, 4, and 8 kg m-3) and two seed origins (Viçosa-MG and Linhares-ES), with
four replicates and 126 seedlings per plot. At 60, 90, and 120 days after emergence, seedlings
were collected to measure variables related to emergence, growth, and nutrition. The greatest
growth and best nutritional status were found for seedlings originated from seeds collected in
Linhares at CRF dose of 8 kg m-3. On the other hand, seedlings originated from seeds collected
in Viçosa showed low emergence and high plant mortality.
