Abstract

We investigated different dormancy breaking methods and substrates for Samanea tubulosa seedlings. Four substrate formulations were tested: SCO: commercial substrate; BBA: decomposed babassu biomass + soil (1:1); BBU: buriti biomass + soil (1:1); and BCA: carnauba bagana + soil (1:1), and three dormancy breaking methods: EM: mechanical scarification; IA: immersion in water; and EQ: chemical scarification. The highest seedling emergence was in BCA substrate with chemical scarification. BCA and SCO provided the highest average seedling height, root length, root volume, root density, diameter at neck height, number of leaves, aboveground dry mass, belowground dry mass, and Dickson quality index values. Therefore, BCA can be used as a substrate for the production of S. tubulosa seedlings, and the immersion in water method is optimal when combined with a BBU substrate.
