Resumo
Araticum (Annona crassiflora M.) is a species of native fruit of the Annonaceas family
which grows in the whole State of Goiás, Brazil. The objective of this work was to evaluate the germination of araticum
fruits seeds collected of natural populations of plants located in five areas of Cerrado of the State of Goiás, treated with
gibberellic acid (GA 3 ). It was determined speed of emergency to each three days and the germination percentage of seeds,
fruits of 75 plants. The used delineation was of randomized blocks, with four blocks and 75 treatments. Each parcel was
composed for 50 seeds of one same plant, totalizing 15.000 seeds. The data had been submitted to the variance analysis
and applying test F. It had germination of the majority of the seeds of the plants of each area, showing that, independently
of the vigor, the used dosage of gibberellic acid was adjusted. On average the germination percentage varied of 12.81% in
Vila Propicio 28.81% in Campos Belos. In plant 10 of Campos Belos observed it bigger average for germination (66%)
and the average minor of necessary days for the emergency (49 days). The seeds proceeding from of araticum fruits of the
five areas of Cerrado in study, present differences in the germination percentage and the speed of emergency. The
germination differences occur between plants in the area and areas.
