dc.description.abstract | The aim of the present study was to determine the most suitable pretreatment to enhance the tetrazolium test in seeds of the Epidendrum genus. Initially, mature capsules were harvested at El Escorial village, in the municipality of Pamplona, Colombia. Subsequently, the seeds were subjected to five pretreatments: deionized water, 0.5% NaClO, 1.0% NaClO, 10.0% sucrose and a control group. Using the syringe method with cloth filter, the seeds were rinsed with distilled water and subjected to two concentrations of tetrazolium solution (0.25%, 1.0%) and three exposure times (6 h, 24 h and 48 h). Finally, the tetrazolium viability test results were correlated with the in vitro germination test. It was found that the use of deionized water improves the efficiency of the tetrazolium test in seeds of Epidendrum fimbriatum and E. microtum; as in seeds of E. elongatum when using 1.0% tetrazolium for 24 h. Similarly, a high correlation was found between viability and germination, using deionized water and 10.0% sucrose, with homogeneous results with each other. | eng |
dc.description.abstract | O objetivo do presente estudo foi determinar o pré-tratamento mais adequado para aprimorar a metodologia do teste de tetrazólio em sementes do gênero Epidendrum. Inicialmente, cápsulas maduras foram coletadas na vila de El Escorial, no município de Pamplona, Colômbia. Em seguida, as sementes foram submetidas a cinco pré-tratamentos: água deionizada, NaClO a 0,5%, NaClO a 1,0%, sacarose a 10,0% e um controle. Utilizando o método de seringa com filtro de pano, as sementes foram lavadas com água destilada e submetidas a duas concentrações de solução de tetrazólio (0,25% e 1,0%) e três tempos de exposição (6 h, 24 h e 48 h). Finalmente, os resultados do teste de viabilidade do tetrazólio foram comparados ao teste de germinação in vitro. Verificou-se que o uso de água deionizada melhora a eficiência do teste de tetrazólio em sementes de Epidendrum fimbriatum e de E. microtum, assim como em sementes de E. elongatum ao usar 1,0% de tetrazólio por 24 h. Da mesma maneira, foi encontrada alta correlação entre viabilidade e germinação, utilizando água deionizada e 10,0% de sacarose, com resultados homogêneos. | por |
