Resumo: | The objective of this work was to carry out the morphobiometric characterization of fruits, seeds and seedlings of Khaya grandifoliola. The fruits were characterized by evaluating length, diameter and thickness of the pericarp, and the seeds by length, width, thickness, weight of 1,000 seeds and moisture content. Germination and seedling morphology were also analyzed. The data were submitted to descriptive statistical analysis and the seeds grouped into classes, through a frequency distribution, according to their length. The fruits of K. grandifoliola are capsule-type with longitudinal dehiscence, polyspermic, with approximately 48 seeds of intermediate predominance and flattened shape, with a slight extension in the tegument and slightly winged. The seeds vary in length from 19.84 to 38.31 mm, width from 18.10 to 20.77 mm and thickness from 2.25 to 2.82 mm, weight of 1,000 seeds was 274.12 g and moisture content was 6.8%. Primary root protrusion is visible from the fifth day after sowing, and germination is of the cryptocotyledon hypogeal type, with seedling formation at 14 days, with reddish-green primary leaves. The results obtained are important to support methodologies definition and future additions to the RAS on the K. grandifoliola species. |

Objetivou-se neste trabalho realizar a caracterização morfobiométrica de frutos, sementes e plântulas de Khaya grandifoliola. Os frutos foram caracterizados pela avaliação do comprimento, diâmetro e espessura do pericarpo, e as sementes pelo comprimento, largura, espessura, peso de 1.000 sementes e grau de umidade. Foi também analisada a morfologia da germinação e das plântulas. Os dados foram submetidos à análise estatística descritiva e as sementes agrupadas em classes, por meio de uma distribuição de frequência, conforme o seu comprimento. Os frutos de K. grandifoliola são do tipo cápsula com deiscência longitudinal, polispérmicos, com aproximadamente 48 sementes de predominância intermediária e forma achatada, com leve extensão no tegumento e levemente alada. As sementes possuem comprimento variando de 19,84 a 38,31 mm, largura de 18,10 a 20,77 mm e espessura de 2,25 a 2,82 mm, peso de 1.000 sementes de 274,12 g e grau de umidade de 6,8%. A protrusão da raiz primária é visível a partir do quinto dia após a semeadura, e a germinação é do tipo hipógea criptocotiledonar, com formação de plântulas aos 14 dias, com folhas primárias de coloração verde-avermelhada. Os resultados obtidos são importantes para auxiliar na definição de metodologias e futuros acréscimos nas RAS sobre K. grandifoliola.Embrapa Florestas2023-10-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionTextoapplication/octet-streamhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/218210.4336/2023.pfb.43e202102182Pesquisa Florestal Brasileira; v. 43 (2023)Pesquisa Florestal Brasileira; Vol. 43 (2023)1983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/2182/1703Copyright (c) 2023 Marcos Lopes de Campos, Andréia Márcia Santos de Souza David, Deyvisson Rodrigues Pinto, Ruthelly Viereca Sena Rocha, Franson Ronner Pereira Alves, Josiane Cantuária Figueiredo, Eliene Almeida Paraizohttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessCampos, Marcos Lopes de David, Andréia Márcia Santos de SouzaPinto, Deyvisson Rodrigues Rocha, Ruthelly Viereca SenaAlves, Franson Ronner Pereira Figueiredo, Josiane Cantuária Paraizo, Eliene Almeida 2023-03-16T12:47:49Zoai:pfb.cnpf.embrapa.br/pfb:article/2182Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2023-03-16T12:47:49Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
