Resumo: | This study aimed to characterize the morphology of seeds and seedlings and evaluate the germination of seeds of Albizia edwallii submitted to different substrates and temperatures. In physical characterization were evaluated thousand seed weight, the number of seeds per kilogram and moisture content. To determine the morphological characteristics, it was evaluated the biometry of 50 seeds, as well as its internal and external characteristics. Germination was conducted at three temperatures (20 ° C, 25 ° C and 30 ° C) and three substrates (sand, vermiculite and blotting paper) with five replications of 40 seeds per treatment, in a factorial 3 x 3 and completely randomized design. The variables were germination percentage, germination rate index, mean germination time, and synchronization index. The thousand seed weight was 47.7 g, while the number of seeds per kilo was 20.964 for the moisture content of 13.1%. The seeds have an elliptical shape, no endosperm and have persistent funiculus. Germination is epigeal, and the seedling is phanerocotylar being fully formed at 15 days. Temperatures of 20 ° C and 25 ° C provide the highest germination rates, 42 and 38%, respectively, and germination speed index (GSI). The use of sand as a substrate provided better germination percentage than the other substrates. Thus, it is recommended to use sand as a substrate and temperatures of 20 ° C and 25 ° C in A. edwalli germination tests. |

Na caracterização física foram avaliados o peso de mil sementes, número de sementes por quilo e grau de umidade. Para a determinação das características morfológicas foi avaliada a biometria de 50 sementes, bem como as suas características internas e externas. A germinação foi conduzida sob três temperaturas (20 °C, 25 °C e 30 °C) e três substratos (areia, vermiculita e papel mata-borrão), com cinco repetições de 40 sementes por tratamento, em esquema fatorial 3 x 3 e delineamento inteiramente casualizado. As variáveis avaliadas foram porcentagem de germinação, índice de velocidade de germinação, tempo médio de germinação e índice de sincronização. O peso de mil sementes foi de 47,7 g, enquanto que o número de sementes por quilo foi de 20.964 para o grau de umidade de 13,1%. As sementes possuem forma elíptica, não apresentam endosperma e possuem funículo persistente. A germinação é epígea e a plântula é fanerocotiledonar, estando completamente formada aos 15 dias. As temperaturas de 20 °C e 25 °C propiciaram os maiores percentuais de germinação, quais sejam, 42 e 38%, respectivamente, e índice de velocidade de germinação (IVG). A utilização de areia como substrato proporcionou percentuais de germinação superiores aos demais substratos avaliados. Assim, recomenda-se a utilização de areia como substrato e as temperaturas de 20 °C e 25 °C para os testes de germinação de A. edwalli.Universidade Federal Rural do Semi-Árido2015-08-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/452910.1590/1983-21252015v28n319rcREVISTA CAATINGA; Vol. 28 No. 3 (2015); 166-173Revista Caatinga; v. 28 n. 3 (2015); 166-1731983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAporhttps://periodicos.ufersa.edu.br/caatinga/article/view/4529/pdf_288Copyright (c) 2023 Revista Caatingainfo:eu-repo/semantics/openAccessDuarte, Manoela MendesMilani, Jaçanan Eloísa de FreitasBlum, Christopher ThomasNogueira, Antonio Carlos2023-06-30T16:51:34Zoai:ojs.periodicos.ufersa.edu.br:article/4529Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:17.025982Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
