Abstract

The study of seedling production of native species with timber potential is very important because of the need for replacement of these species due to strong commercial logging, recovery of degraded areas and ornamental use. The objective of this study was to evaluate the initial growth of three native forest species seedlings, mulateiro (Calycophyllum spruceanum Benth.), amarelão (Aspidosperma parvifolium A.DC.) and freijó [Cordia alliodora (Ruiz & Pav.) Cham.], using different substrates composed of agro forestry waste. The substrates tested were soil - Control (T), sifted Açaí waste (RAP), (T)+(RAP) (1:1 v/v) and bark of crushed peanuts (CAT) + bark of crushed Brazilian nut (CCT) + soil (T) (1:1:1 v/v/v). The experiment was a completely randomized design factorial 3×4 (three species x four substrates), with 12 treatments and five replicates of two seedlings, totaling 120 samples, which were monitored for 120 days. The shoot height and stem diameter of the seedlings were monthly measured, and dried weights of shoot, root and total biomass were evaluated. Among the substrates studied, the composition CAT+CCT+T was adequate to grow seedlings of amarelão, freijó and mulateiro. However, the last species had greatest development in soil substrate (T).
