Resumo: Knowledge concerning natural regeneration strategies is important due to the effect of natural regeneration on the local ecosystem. The aim of this study was to examine the ecophysiological aspects of the Peltophorum dubium aerial seed bank. Fruits were harvested monthly, before and after seed maturation, from selected trees in the municipality of Lavras, MG, Brazil, for determination of moisture content, acquisition of tolerance to desiccation, seed viability, maintenance of dormancy, and mean germination time. Physiological maturity of the species was attained in June, when low moisture content, maximum dry matter, and high germination percentage were observed. We found that there was no change in dormancy, in germination percentage, or in the protein profile of seeds during the period they remained in the aerial seed bank. The P. dubium species creates an aerial seed bank of short serotiny, with fruits remaining attached to the tree for 9 months.

Objetivou-se estudar o comportamento do banco de sementes aéreo de P. dubium. Os frutos foram colhidos mensalmente antes e após a maturação das sementes em matrizes localizadas no município de Lavras - MG. Mensalmente, foram determinados o conteúdo de água, aquisição da tolerância a dessecação, viabilidade das sementes, manutenção da dormência e tempo médio de germinação. Verificou-se que a maturidade fisiológica da espécie ocorreu no mês de junho, quando foi observado baixo conteúdo de água, máxima matéria seca, e alta porcentagem de germinação. Verificou-se que não houve alteração na dormência, porcentagem de germinação e no perfil proteico de sementes durante o período em que permanecem no banco de sementes aéreo. A espécie P. dubium forma banco de sementes aéreo de curta serotinosidade, com frutos permanecendo presos à planta por 9 meses.Associação Brasileira de Tecnologia de Sementes (ABRATES)2018-07-25T20:41:24Z2018-07-25T20:41:24Z2017info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfSILVA, G.
