Resumo: The objective of this study was to evaluate the physiological quality of Jacaranda micranta Cham. seeds, by electrical conductivity test. We used three lots of seeds, stored for different periods. Electrical conductivity tests were conducted at different amounts of seeds and deionised water for soaking, and then they were associated with germination and vigour data. It was observed that the longer the seeds were storage, the greater their electrical conductivity, and therefore the lower were their germination vigour. It was also observed that different quantities of seeds and soaking water did not present significant difference, so it is recommended to use 50 seeds in 75 mL of deionised water.

Foram utilizados três lotes de sementes, armazenados por diferentes períodos. O teste de condutividade elétrica foi realizado em diferentes quantidades de sementes e água deionizada para embebição, sendo depois associados a dados de germinação e vigor. Foi observado que quanto maior o tempo de armazenamento das sementes, maior seu valor de condutividade elétrica e, consequentemente, menor seu vigor de germinação. Verificou-se também que as diferentes quantidades de sementes e de volume de água na embebição não apresentam diferença significativa. Assim, recomenda-se a utilização de 50 sementes em 75 mL de água deionizada.Embrapa Florestas2021-11-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/89410.4336/2016.pfb.36.85.894Pesquisa Florestal Brasileira; v. 36 n. 85 (2016): jan./mar.; 79-83Pesquisa Florestal Brasileira; Vol. 36 No. 85 (2016): jan./mar.; 79-831983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/894/468Copyright (c) 2016 Gabriela Fernanda Souza, Juliana Garlet, Pricila Delazerihttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessSouza, Gabriela FernandaGarlet, JulianaDelazeri, Pricila2021-11-17T13:34:26Zoai:pfb.cnpf.embrapa.br/pfb:article/894Revistahttps://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:2021-11-17T13:34:26Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
