Resumo: | The dormancy is an intrinsic seed phenomenon, functioning as natural mechanism of resistance to adverse environmental factors. Germination will occur only when it is overcome and the environmental conditions are favorable for seedling growth. The objective of this study was to analyze the effect of treatments to overcome dormancy in the structure of Apuleia leiocarpa seed testing by scanning electron microscopy. The pre-germination methods to overcome dormancy were: non-scarified seeds (control), immersion in sulfuric acid 75 and 98% for three and nine minutes and immersion in hot water at 80°C for 30 seconds. The seeds were submitted to analysis in microscopy and were evaluated by the germination test. The treatments were effective in breaking the exotesta seed of sugar cane juice, wherein the high acid induced increase in germination. The heated water caused the death of seeds. |

A germinação só ocorrerá quando esta for superada e as condições ambientais forem favoráveis ao crescimento das plântulas. O objetivo deste trabalho foi analisar o efeito de tratamentos para superação da dormência na estrutura da testa de sementes de Apuleia leiocarpa pela microscopia eletrônica de varredura. Os métodos pré-germinativos para superação da dormência foram: sementes não escarificadas (testemunha), imersão em ácido sulfúrico 75 e 98% por três e nove minutos e imersão em água aquecida a 80ºC por 30 segundos. As sementes foram submetidas às análises em microscopia e foram avaliadas pelo teste de germinação. Os tratamentos foram eficientes em romper a exotesta das sementes de garapa, sendo que o ácido promoveu elevado incremento na germinação. A água aquecida causou a morte das sementes.Universidade Federal de Santa Maria2017-08-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2868110.5902/1980509828681Ciência Florestal; Vol. 27 No. 3 (2017); 1061-1068Ciência Florestal; v. 27 n. 3 (2017); 1061-10681980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/28681/16191Copyright (c) 2017 Ciência Florestalinfo:eu-repo/semantics/openAccessCastro, Dayene Schiavon deAraujo, Eduardo FontesBorges, Eduardo Euclydes de LimaAmaro, Hugo Tiago Ribeiro2017-08-31T18:36:04Zoai:ojs.pkp.sfu.ca:article/28681Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-08-31T18:36:04Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
