Abstract

This study aimed to evaluate the effect of substrates in the emergence and early development of Baru seedlings. The experiment was performed in a greenhouse in a completely randomized design with five treatments (substrates) and four replications. The substrates were: S1) Oxisol; S2) Oxisol + washed sand (1: 1 v: v); S3) washed sand; S4)  Oxisol + washed sand + manure (1: 1: 1 v: v: v); S5) Oxisol + sand washed + poultry litter (1: 1: 1 v: v: v). The emergence, emergence speed index, seedling height (SH), stem diameter (SD), root length, shoot dry mass (SDM), root dry mass (RDM), SH/SD and SDM/RDM ratios and the Dickson quality index were evaluated. The emergence and early development of seedlings were influenced by the type of substrate. The Oxisol substrate is the most efficient for the early development of Baru seedlings.

Key words: Dipteryx alata Vog, emergence, germination, reforestation.
