Resumo: The Solanum torvum species can grow in soils with a heavy load of nematodes and pathogenic fungi. It is currently much in demand in intensive agriculture as a rootstock of Solanaceae species, such as eggplant and tomato. This study aimed at comparing treatments, in order to determine the best method to accelerate the germination of S. torvum seed batches. Three seed batches were submitted to four treatments to overcome dormancy (water, potassium nitrate, gibberellic acid and pre-imbibition in gibberellic acid). The first germination count, germination percentage, germination speed index, mean germination time and mean germination speed were assessed. Treatments with gibberellic acid, with either pre-imbibition or only moistened substrate, exhibited the best germination speed index, mean germination time and mean germination speed. The final germination percentage showed a significant interaction between treatments and seed batches. Therefore, the treatments affect the final germination in a batch-dependent manner.

Atualmente, é muito demandada na agricultura intensiva como porta-enxerto de espécies de Solanaceae, tais como berinjela e tomate. Objetivou-se comparar tratamentos, buscando o melhor método para acelerar a germinação de lotes de sementes de S. torvum. Três lotes de sementes foram submetidos a quatro tratamentos para superação de dormência (água, nitrato de potássio, ácido giberélico e pré-embebição em ácido giberélico). Avaliaram-se a primeira contagem de germinação, porcentagem de germinação, índice de velocidade de germinação, tempo médio de germinação e a velocidade média de germinação. Os tratamentos com ácido giberélico, com pré-embebição ou apenas com o substrato umedecido, apresentaram os melhores índices de velocidade de germinação, tempo médio de germinação e velocidade média de germinação. A porcentagem final de germinação apresentou interação significativa entre tratamentos e lotes de sementes. Portanto, os tratamentos afetam a germinação final de maneira dependente do lote.Escola de Agronomia - Universidade Federal de Goiás2017-01-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/43134Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 46, n. 4, Oct./Dec. 2016; 464-469Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 46, n. 4, out./dez. 2016; 464-469Pesquisa Agropecuária Tropical; v. 46, n. 4, out./dez. 2016; 464-4691983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/43134/22315Copyright (c) 2017 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessCutti, LuanKulczynski, Stela Maris2020-07-13T18:22:49Zoai:ojs.revistas.ufg.br:article/43134Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:15.399496Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
