“…Significant variations in biometric traits among ebony trees in the Colombian Caribbean suggest the existence of genetic variability, allowing genetic progress to be achieved in plant breeding programs through the selection of trees with desirable fruit and seed characters(Dos-Santos et al, 2018;Espitia et al, 2018). Similar results were reported in forest species of the same ebony family byOkello et al (2018) in Tamarindus indica L. and other economically important species such as Hymenae acourbaril L (Ristau et al, 2018),. Bursera simplex Rzed.…”

“…Studies of associations between traits based on their phenotypic and genetic correlations make it possible to improve the efficiency of selection in genetic improvement programs, improve the quality of the products, and achieve greater genetic progress (Pérez-Pelea et al, 2018;Araméndiz-Tatis et al, 2020;Araméndiz-Tatis et al, 2021). Several authors have developed correlation studies between the biometric traits of the fruit and its seeds in forest species (Leão et al, 2017;Dos-Santos et al, 2018;Ristau et al, 2018).…”

Caesalpinia ebano is a tropical tree from Colombia; its conservation status is in the endangered category since the remaining populations are suffering genetic erosion. The objective of this study was to estimate the phenotypic (rF) and genetic (rG) correlations among biometric fruit and seeds traits, and the path analysis for the fruit weight. Ten trees (treatments) were evaluated under the random effects model, with 10 fruits/tree as replications. There was significant variability between trees for seven quantitative traits. The fruit weight showed genetic correlations with six traits (0.56* > rG < 1.00**). The number and weight of the seeds per fruit showed high genetic correlations with five traits (rG ≥ 0.85**). The weight of the seeds per fruit exerted direct and indirect effects of greater importance in determining the fruit weight. It is possible to improve the production and physiological quality of the seed by directly selecting trees with fruits of greater seed weight.

The present study establishes the following research problem: Can different concentrations of Acadian®, Stimulate®, and Trichoderma spp. be effective in promoting the emergence and vigor of Hymenaea courbaril seedlings with or without mechanical scarification? The experimental design used was completely randomized, in a 4 x 3 x 2 factorial scheme, corresponding to four concentrations (0, 5.0, 10.0, and 15.0 mL.L-1), three hormones (Acadian®, Stimulate® and Trichoderma spp.), with and without mechanical scarification, with four replicates, each of which consisting of 25 seeds. Acadian® at a concentration of 5.0 mL.L-1 in scarified seeds of H. courbaril leads to a greater increase in the percentage of emergence and percentage of normal seedlings. Stimulate® at concentrations of 10.0 and 15.0 mL.L-1 is efficient in obtaining more than 85% emergence seedlings with seeds subjected to mechanical scarification. Trichoderma spp. from 9.0 mL.L-1 does not favor gains in the percentage of normal seedlings of Hymenaea courbaril grown from seeds with and without mechanical scarification. The dose of maximum technical efficiency (DMTE) of the bioregulator Acadian® is 8.50 mL.L-1 and, in scarified seeds of H. courbaril, it increases the percentage of seedling emergence.
