Descripción
Sumario:The aim of this study was to evaluate the influence of the extraction and imbibition period on the germination of tucumã (Astrocaryum aculeatum Meyer, Arecaceae) seeds. After cleaning and drying the pyrenes, the endocarp was broken and removed to liberate the seeds that, before sowing, were soaked in water for 0, 3, 6, 9, 12 and 15 days. The germination was superior to 58%, confirming the possibility of extracting the endocarp without damaging the viability of the seeds. The seeds submitted to nine days of soaking, had a moisture content of 30%, obtained better germination (70%) and index of germination velocity, with mean time of germination of 104 days. The removal of the endocarp and the soaking of seeds accelerated and increased the germination.
