Summary: | The Sapindus saponaria L. it is a species that possesses propagation just for seeds and her germination tax is relatively moderate the drop. Therefore, it was aimed at to evaluate different treatments pre-germinating in the overcoming dormancy of the numbness of seeds of this species. The work was driven in atmosphere protected in the Federal University of Campina Grande, in Pombal, Paraíba. The seeds were desinfested with hipoclorito to 2% for five minutes, washed in running water and submitted to the following treatments pre-germinating: intact (witnesses - T1) seeds; manual escarification with aid of sandpaper of water nº 100 on the opposite side to the micropyle (T2); chemical escarificação through the immersion in sulfuric acid to 98% Shovel, during 10, 30 and 60 minutes (T3, T4 and T5, respectively) and physical escarification through the immersion in hot water to 80 ºC for five minutes, following by thermal shock in cold water to 5 ºC for more five minutes (T6). A completely randomized design with four replicates. The seeds were submitted to the emergency tests in sand, index of emergency speed, plant height, root length, mass dries of the aerial part and of root and percentage of hard seeds. The job of the manual scarification with sandpaper of water nº 100 on the opposite side to the micropyle of the seeds is the treatment recommended by being simpler and of larger efficiency, seeking the preservation of the physiologic quality of the seeds and a better vegetative development. |

Portanto, objetivou-se avaliar diferentes tratamentos pré-germinativos na superação da dormência de sementes desta espécie. O trabalho foi conduzido em ambiente protegido na Universidade Federal de Campina Grande, em Pombal, Paraíba. As sementes foram desinfestadas com hipoclorito a 2% durante cinco minutos, lavadas em água corrente e submetidas aos seguintes tratamentos pré-germinativos: sementes intactas (testemunhas - T1); escarificação manual com auxílio de lixa d`água nº 100 no lado oposto à micrópila (T2); escarificação química por meio da imersão em ácido sulfúrico a 98% Pa, durante 10, 30 e 60 minutos (T3, T4 e T5, respectivamente) e escarificação física por meio da imersão em água quente a 80 ºC por cinco minutos, seguida de choque térmico em água gelada a 5 ºC por mais cinco minutos (T6). Empregou-se o delineamento inteiramente casualizado com quatro repetições. As sementes foram submetidas aos testes de emergência em areia, índice de velocidade de emergência, altura de planta, comprimento de raiz, massa seca da parte aérea e de raiz e porcentagem de sementes duras. O emprego da escarificação manual com lixa d'água nº 100 no lado oposto à micrópila das sementes é o tratamento recomendado por ser mais simples e de maior eficiência, visando a preservação da qualidade fisiológica das sementes e um melhor desenvolvimento vegetativo.Editora Verde2018-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfapplication/pdfimage/jpeghttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/528610.18378/rvads.v13i2.5286Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 13 No. 2 (2018); 246 - 249Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 13 Núm. 2 (2018); 246 - 249Revista Verde de Agroecologia e Desenvolvimento Sustentável; v. 13 n. 2 (2018); 246 - 2491981-8203reponame:Revista Verde de Agroecologia e Desenvolvimento Sustentavelinstname:Grupo Verde de Agroecologia e Abelhas (GVAA)instacron:GVAAporhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/5286/5862https://www.gvaa.com.br/revista/index.php/RVADS/article/view/5286/5863https://www.gvaa.com.br/revista/index.php/RVADS/article/view/5286/9363https://www.gvaa.com.br/revista/index.php/RVADS/article/view/5286/9365Copyright (c) 2018 Genilson Lima Diniz et al.info:eu-repo/semantics/openAccessDiniz, Genilson LimaSilva, Joseano Graciliano daLopes, Kilson Pinheiro2021-06-14T13:14:17Zoai:ojs.gvaa.com.br:article/5286Revistahttps://www.gvaa.com.br/revista/index.php/RVADS/PUBhttps://www.gvaa.com.br/revista/index.php/RVADS/oairvadsgvaa@gmail.com || patriciomaracaja@gmail.com || revistaverde1@gmail.com || suporte@antsoft.com.br1981-82031981-8203opendoar:2024-03-06T12:59:22.662579Revista Verde de Agroecologia e Desenvolvimento Sustentavel - Grupo Verde de Agroecologia e Abelhas (GVAA)false |
