Resumo: | Socoró is a fruit tree often found on the banks of rivers, whose fruits are appreciated by aquatic fauna, with potential for use in the recovery of riparian forest. This work aimed to evaluate the biometrics and emergence of seeds of different socoró genotypes, as well as describe and illustrate the seedling in development, and to classify the seeds according to desiccation tolerance. Initially, biometrics and emergency test were evaluated, following a completely randomized design (CRD), with four treatments (genotypes) and four replicates. Seedling development was monitored from the appearance of the primary root to the of expanded second eophyll. For the classification of seeds according to desiccation tolerance, an emergency test in CRD was installed, with four treatments (moisture contents: 36.9; 22.3; 10.7 and 5.3%) and four replicates. Additionally, seeds with moisture contents of 5.3% were stored for three months at temperature of -18 °C, and subsequently subjected to the emergence test. The genotypes showed different behaviors with respect to seed biometry, emergence, emergence speed index, abnormal seedlings, dormant and dead seeds. Germination is hypogeal, cryptocotyledon and unipolar type, with the emission of the primary root at 24 days and the expansion of the second eophyll at 52 days after sowing. The seeds tolerate desiccation to a moisture level of 5.3%, plus cooling for three months at -18 ºC. Socoró genotypes differ in biometry, emergence, vigor and dormancy seeds. The seedling structures can assist in the identification of the species in the field, or in laboratory analysis. The seeds have orthodox behavior. |

Este trabalho teve por objetivo avaliar a biometria e a emergência de sementes de diferentes genótipos de socoró, bem como descrever e ilustrar a plântula em desenvolvimento, e classificar as sementes quanto a tolerância ao dessecamento. Inicialmente, foram avaliadas a biometria e a emergência das sementes, seguindo o delineamento inteiramente casualizado (DIC), com quatro tratamentos (genótipos) e quatro repetições. O desenvolvimento das plântulas foi monitorado desde o aparecimento da raiz primária até o segundo eofilo expandido. Para a classificação das sementes quanto a tolerância ao dessecamento, instalou-se teste de emergência em DIC, com quatro tratamentos (graus de umidade das sementes: 36,9; 22,3; 10,7 e 5,3%) e quatro repetições. Adicionalmente, sementes com grau de umidade de 5,3% foram armazenadas, por três meses, sob temperatura de -18 °C, e, posteriormente, submetidas ao teste de emergência. Os genótipos apresentaram comportamentos distintos com relação a biometria das sementes, emergência, índice de velocidade de emergência, plântulas anormais, e sementes dormentes e mortas. A germinação é do tipo hipógea, criptocotiledonar e unipolar, com a emissão da raiz primária aos 24 dias e expansão do segundo eofilo aos 52 dias após a semeadura. As sementes toleram o dessecamento até o grau de umidade de 5,3%, mais resfriamento por três meses a -18 ºC. Os genótipos de socoró diferem quanto a biometria, emergência, vigor e dormência das sementes. As estruturas da plântula podem auxiliar na identificação da espécie no campo, ou em análises laboratoriais. As sementes apresentam comportamento ortodoxo.Universidade Federal Rural da Amazônia/UFRA2021-01-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionTextoapplication/pdfhttps://ajaes.ufra.edu.br/index.php/ajaes/article/view/3352Amazonian Journal of Agricultural Sciences Journal of Agricultural and Environmental Sciences; Vol 64 (2021): RCA AJAESRevista de Ciências Agrárias Amazonian Journal of Agricultural and Environmental Sciences; v. 64 (2021): RCA AJAES2177-87601517-591Xreponame:Revista de Ciências Agrárias (Belém.
