Teste de tetrazólio em sementes de timbaúba

Abstract: ResumoO teste de tetrazólio tem se mostrado uma alternativa promissora na determinação da viabilidade e do vigor da semente de espécies florestais pela qualidade e rapidez na obtenção dos dados. Dessa forma, o presente trabalho foi desenvolvido objetivando-se padronizar a metodologia de condução do teste de tetrazólio para a avaliação da qualidade fisiológica de lotes de sementes de timbaúba. Para avaliar qualidade fisiológica das sementes os quatro lotes foram submetidos às seguintes determinações: teor de ág… Show more

“…For seeds of Eugenia uniflora L., Kaiser et al (2014) recommend the tetrazolium test at 0.5% for 2 hours at 30 °C. And for seeds of Pacara Earpod Tree, Nogueira et al (2014) recommend seeds immersion in tetrazolium solution at 0.075% at 35 °C for three hours.…”

“…A concentration of 0.07% TZ was recommended, e.g., for Enterolobium contortisiliquum (Vell.) Morong (Nogueira et al, 2014), Poecilanthe parviflora B. (Pinto et al, 2008) and Mouriri elliptica Mart.…”

“…Intense staining may also result in misinterpretation, as shown for Enterolobium contortisiliquum (Vell.) Morong seeds (Nogueira et al, 2014). The individual assessment of seed viability, with a solution of 0.10% TZ, needs about 20 ml of solution per seed, totalling 2 L for 100 seeds, corresponding to 2 g of TZ.…”
