Anatomy and Germination of Erythrina velutina Seeds under a Different Imbibition Period in Gibberellin

The knowledge of the physiological aspects Caatinga’s vegetal species is extremely important for preserving this biome, which suffers with human impacts, mainly to select propagation methods. Erythrina velutina a Brazilian tree, generally found in Caatinga, medical and forestry potential. objective paper was determine best soaking period gibberellin solution achieve highest germination evaluate internal anatomy by digital microtomography E. seeds. design completely randomized consisted eight treatments: 1, 3, 6, 12, 24 48 h soaking, scarified seeds control no-scarified Digital efficient describing distinguishing their tissues. There no significant difference between treatments at different times, as gibberellic acid did not influence germination; only presented lower percentage, differing from other treatments. study presents evidence that do require exogenous use acid, but scarification process. In addition, can be useful understanding seeds, especially forest species, contribute future studies plant species.
