Abstract
Maricá (Mimosa bimucronata (D.C.) O. Kuntze.) is a species that presents great importance in reforestation programs, in the recovery of permanent preservation areas, landscaping projects and is considered soil improver, being recommended for erosion and for planting on flooded land. The objective of the present study was to evaluate the viability of the seeds of M. bimucronata by the tetrazolium test and to determine the crude oil content and the percentage composition of fatty acids. The experiments were conducted at the Plant Propagation Laboratory of the Agricultural Sciences Center (CECA) of the Federal University of Alagoas (UFAL), located in the municipality of Rio Largo, Alagoas, Brazil. The obtained data submitted to the analysis of variance and the comparison between the means of viable seeds for each of the combinations in the tetrazolium test were performed by the Dunnett test at 5%. The concentration of 0.075% tetrazolium salt for two hours at 35 °C is an efficient combination for evaluating the viability of M. bimucronata seeds. The oil content was 2.75%, with unsaturated fatty acids prevailing (63.8%).
