The objective of this work was to investigate the effect of substrate, color and size on the germination and vigor of Melanoxylon brauna seeds. It was performed two essays. In the first, the seeds were classified by color (light and dark) and size (small and large). In the second essay, it was investigated the influence of substrates on sand, between sand, above paper, between paper and in paper rolls, type germitest. In both essays, the seeds were maintained in controlled conditions (light and temperature) during 10 days. The percentage of germination and germination speed index (GSI) were calculated. Furthermore, it was determined the weight of 1,000 seeds and the germination of the species was characterized by observation until the seedling formation.... |
