Resumo: | Anadenanthera colubrina (Vellozo) Brenan is a Mimosaceae tree used for pasture afforestation and its wood produces good quality parquet blocks, slats, packing, charcoal and firewood. This work aimed to study the species seed influence under accelerated aging treatments in order to evaluate seed vigour through germination test. The aging camera method was adopted with temperatures of 40 ± 2oC and humidity around 95%, with stay time zero (T1); 24 (T2); 48(T3); 72 (T4) and 96 hours (T5). Statistic design used was completely random, with four replicate and 25 seeds per treatment. Germination test was carried out under 30oC temperature and continuous light with paper filter moistened as substrate. First counting was conducted on the fifth day and the last on the ninth day after trial establishment. Fresh seed germination was 98% and water content was 8,1%. It was observed that control treatment (T1), after 14 months of storge showed 75% germination and the others treatments showed germination between 32 and 21%. Accelerated aging caused loss of viability on the observed seeds, low percentage of normal plants and high percentage of deteriorated seeds. Accelerated aging decreased the seed germination speed. |

O objetivo deste trabalho foi estudar a influência do teste de envelhecimento acelerado no vigor de sementes dessa espécie. O ensaio foi conduzido utilizando o método da câmara de envelhecimento, com temperatura de 40 2oC e umidade relativa de 95%, com tempo de permanência zero (T1); 24 (T2); 48 (T3); 72 (T4) e 96 horas (T5). O delineamento utilizado foi o inteiramente casualizado, com quatro repetições de 25 sementes, por tratamento. O teste de germinação foi realizado à temperatura de 30oC, com luz constante, tendo como substrato rolo de papel. A primeira contagem foi efetuada no quinto dia e a última no nono dia da instalação. A germinação das sementes frescas foi de 98% e o teor de água de 8,1%. Observou-se que a testemunha (T1), após 14 meses de armazenamento, apresentou germinação de 75% e os demais tratamentos (T2, T3, T4, T5) apresentaram percentuais variando entre 32 e 21%. O envelhecimento acelerado provocou a perda da viabilidade das sementes estudadas. Registrou-se baixa percentagem de plântulas normais e alta de sementes deterioradas. O envelhecimento acelerado provocou um declínio na velocidade de germinação das sementes da espécie.Universidade Federal de Santa Maria2005-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/178410.5902/198050981784Ciência Florestal; Vol. 14 No. 1 (2004); 85-90Ciência Florestal; v. 14 n. 1 (2004); 85-901980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1784/1050Garcia, Lucinda CarneiroNogueira, Antônio CarlosAbreu, Daniela C.
