Resumo: Vermiculite is a substrate used in seedling production of forest species and can be an option for the germination test of ipe seeds. The objective of this research was to evaluate the use of vermiculite in the germination test of Tabebuia chrysotricha seeds and to stablish appropriate particle size and moisture for this substrate. Four replications of 20 seeds were sown in soil, sand, paper rolls, and vermiculite with different particle sizes: micron (0.15-0.20 mm), superthin (0.21-0.30 mm), thin (0.30-0.50 mm) and medium (0.50-1.19 mm) moistened with water equivalent to 0.5, 1.0, 1.5 and 2.0 times the weight of the dry subtrate. Germination test was carried out at 30°C. The percentage of normal seedlings was obtained seven days after sowing (first count) and then weekly until 28 days, when abnormal seedlings and dead seeds were also counted. It was concluded that the germination test of ipe seeds can be carried out with thin or medium vermiculite moistened with water equivalent to 1.5 times the dry weight of the substrate. These treatments resulted in higher and faster germination (21 days).

O objetivo deste trabalho foi avaliar o desempenho da vermiculita para o teste de germinação e estabelecer qual granulometria e intensidade de umedecimento deste substrato é mais favorável à germinação de sementes de Tabebuia chrysotricha. A semeadura foi realizada com quatro repetições de 20 sementes em solo, areia, rolo de papel, e em vermiculita de diferentes granulometrias: mícron (0,15-0,20 mm), superfina (0,21-0,30 mm), fina (0,30-0,50 mm) e média (0,50-1,19 mm), umedecidas com um volume de água equivalente a 0,5; 1,0; 1,5 e 2,0 vezes a sua massa seca. O teste de germinação foi conduzido a 30°C, com a primeira contagem das plântulas normais do teste aos sete dias após a semeadura e, as demais semanalmente até os 28 dias, quando foram contabilizados, também, as plântulas anormais e sementes mortas. Foi calculado o tempo médio e a frequência relativa de germinação. O teste de germinação de sementes de ipê-amarelo deve ser conduzido em vermiculita fina ou média umedecida com 1,5 vezes a sua massa em água, condição que permite maior porcentagem de germinação e encerramento do teste em menor tempo (21 dias).UEL2012-05-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa de campo e laboratórioapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/637010.5433/1679-0359.2012v33n2p533Semina: Ciências Agrárias; Vol. 33 No. 2 (2012); 533-540Semina: Ciências Agrárias; v. 33 n. 2 (2012); 533-5401679-03591676-546Xreponame:Semina.
