CARDOSO, Edson de Almeida et al. Emergency of the Erythrina velutina seedlings at different positions and sowing depths. Cienc. Rural [online]. 2008, vol.38, n.9, pp.2618-2621. ISSN 1678-4596.  https://doi.org/10.1590/S0103-84782008000900034.

The aim of this research was to study the influence of the sowing depth and position upon seedling emergency and seed vigor of the coral tree, some germination tests were settled in sand, under protected environment. The treatments were represented by the position and depth of the seed sowings relative to the substratum, as follows: seed with the hilum turned down, upward and to the side at depths 1, 2, 3, 4 and 5cm. Each treatment consisted of four replicates with 25 seeds, and were evaluated by the following tests: emergence, first-counting vigor, emergency speed, length and dry mass of the hypocotyl and roots. According to the results for coral tree, the sowing depth should be between one and two centimeters, whereas the best position was the hilum turned down.
