Resumo: | The objective of this study was to describe the morphological characters of fruits, seeds and seedlings, characterize the germination process and verify that the seed position in the fruit interferes with the seed germination of Poincianella pyramidalis. The fruits were collected from five trees in the Castro Alves, Bahia – Brazil in the area near the remnants of Caatinga sensu stricto and Deciduous Forest. The fruit of Poincianella pyramidalis is a type of legume, polyspermic, dehiscent, measuring on average 9.4 ± 0.08 cm in length and can contain up to 8 seeds per fruit, being the average number of seeds, apparently viable fruits per 100 ± 280 29.8. The seed is ellipsoid, yellowish brown color and smooth, polished and hard, being provided testa and internal tegument, with a length of 1.25 ± 0.004 cm. The embryo is axis, invaginated and straight and there was no presence of endosperm. The weight of 1000 seeds was 106.8 ± 12.4 g. Germination is phanecotylar-epigious began the third day after sowing and the complete formation of the seedling was observed on the ninth day. Seed production of Poincianella pyramidalis in the proximal position is lower compared to other positions. Seed germination is influenced by seed position in the fruit, seeds present in the distal lower seed germination of other positions. |

Os frutos foram coletados de cinco árvores-matrizes em propriedade rural situada no município de Castro Alves - BA - Brasil em área próxima a remanescentes de Caatinga sensu stricto e Floresta Estacional. O fruto de Poincianella pyramidalis é do tipo legume, polispérmico, deiscente, medindo, em média, 9,4±0,08 cm de comprimento, podendo conter até 8 sementes por fruto, sendo o número médio de sementes, aparentemente viáveis, por 100 frutos de 280±29,8. A semente é elipsoide de cor castanho-amarelada e superfície lisa, polida e dura, sendo provida de testa e tegma, com comprimento de 1,25 ± 0,004 cm. O embrião é axial, invaginado e reto e não foi verificada presença de endosperma. O peso de 1000 sementes foi de 106,8 ± 12,4 g. A germinação é epígea fanerocotiledonar, teve início no terceiro dia após a semeadura e a formação completa da plântula foi verificada no nono dia. A produção de sementes de Poincianella pyramidalis na posição proximal é inferior em relação às demais posições. O percentual de germinação é influenciado pela posição da semente no fruto, sementes na posição distal apresentam germinação inferior às sementes das demais posições.Universidade Federal de Santa Maria2016-06-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2273810.5902/1980509822738Ciência Florestal; Vol. 26 No. 2 (2016); 375-387Ciência Florestal; v. 26 n. 2 (2016); 375-3871980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/22738/13422Copyright (c) 2016 Ciência Florestalinfo:eu-repo/semantics/openAccessMendonça, Andrea Vita ReisFreitas, Teresa Aparecida Soares deSouza, Leonardo SilvaFonseca, Mariana Duarte SilvaSouza, Josival Santos2017-04-06T14:06:44Zoai:ojs.pkp.sfu.ca:article/22738Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-06T14:06:44Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
