“…Silva et al (2019) [21] in guava seeds of the white and red variety also verified that the mixture of substrates provided the best viability and vigor results, indicating the organic compound substrates + black sand + commercial substrate and washed sand + rice straw + black soil as the best. Nunes et al (2020) [22], working with Cagaita seeds, verified that, the humus substrates of worm humus + black soil + commercial substrate and commercial substrate + poultry manure + black soli + washed sand provided the highest values of viability and vigor in Cagaita seeds.…”

The Bacaba (Oenocarpus bacaba) belongs to the Arecaceae family, is a palm tree native to the Amazon, in which it is distributed throughout the Amazon basin, mainly in the regions of Pará, Tocantins, Acre, and in southern Maranhão, having as habitat the high virgin forest. The production of quality seedlings depends on several factors, and the composition of substrates is a major factor, because seed germination, root initiation, and rooting are directly linked to the chemical, physical and biological characteristics of the substrate. The experiment was carried out at the Federal Institute of Education - IFTO, Sciences, and Technology of Tocantins, in the city of Gurupi - TO, between September 5, 2018, and December 30, 2018. For the realization of the same, Bacaba seeds (Oenocarpus bacaba) were used, which were purchased at the street fair in the municipality of Gurupi - TO. Root and shoot length, number of leaves, root and shoot dry mass, first emergency count and seedling emergence were evaluated. The substrates: Washed Sand, Commercial Substrate, Pinus Bark + Sawdust Powder + Commercial Substrate, and Worm Humus + Coconut Shell + Commercial Substrate + Sawdust Powder provided the highest values of viability and vigor in Bacaba seeds.

Eugenia dysenterica DC. is a native tree from the Brazilian Savanna known as a genetic resource for its fruits and culinary potential. The knowledge on the genetic variability of agronomic traits is important to support studies on its conservation and domestication. This study aimed to estimate the quantitative genetic parameters of initial growth traits among and within E. dysenterica subpopulations, in provenance and progeny testing, and establish a germplasm collection representative of the species distribution. For that, 25 natural subpopulations were sampled and, within each subpopulation, six mother trees. The progenies were sown in a nursery, in a randomized complete blocks design consisting of 150 progenies, four replications and five plants per plot. The analysis of variance of the initial development traits revealed a greater variability among the progenies within the subpopulation than that observed among the subpopulations. The aboveground biomass represented only 15 % of the total biomass, a recurrent characteristic in Brazilian Savanna species. The estimated heritability and coefficients of genetic variation presented selection potential for the initial development traits, which are important for commercial seedlings production. An in vivo ex situ germplasm collection was established for conservation and breeding purposes, using a sample of four plants from each progeny.
