Germinação de sementes e emergência de plântulas de araticum oriundos do cerrado de Goiás

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.
