RESUMO

The peculiar climatic conditions of the semi-arid area offer plants for the human exploration in natural a way among these, stands out the Spondias tuberosa Arruda Câmara, whose fruit is havested in an extractive and disorganized way, putting in risk its perpetuation. The objective of this study was to verify the storage period of the seeds, the environments and the stage of fruit maturation most adopted to a good propagation of the species. The experiment was conduted in a greenhouse at the Center of Agricultural Sciences, (CCA), Areia, UFPB, PB. The experimental design used was a completely randomized in a factorial scheme (5 x 2 x 4), with four repetitions. The studied variables were the germination percentage, vigour (index of germination speed), number of sprouts, height of plants, diameter and length of the tubers. The seeds maintained under natural environmental conditions, stored for a period of eight months presented higher germination uniformity, germinative potential of 90%, and vigour of 0,505. The most appropriate seeds to optimise germination were those originating from the mature fruits (87,5%) and highly ripened fruits (90%).
