This work aimed to evaluate the seeds germination and vigor of cv Golden papaya fruits after seeds and fruits storage. The papaya fruits were picked from two maturation stage, from Caliman Farm, in Linhares - ES. The fruits were conserved in 25ºC for 10 days and the seeds germination was evaluated at the 0, 2, 6 e 10 days. After extraction and washing of the seeds, the drying was accomplished using an oven-dried with air circulation at 30ºC until they reached 8 to 10% humidity. A part of the seeds was analyzed, immediately, as germination and vigor percentage (first count of germination test and percentage of strong seedling in first count of germination). Another part was stored in packings of the type pouch of flexible aluminum by 30 and 120 days in 15ºC. The experimental design used was completely randomized in 4x3 factorial scheme with four replications. The treatments consisted of four fruits storage period (0, 2, 6 e 10 days), with three seeds storage period (0, 30 and 120 days). The vigour was better availed by first count of germination test than by percentage of strong seedling. There were increase in the seed germination and vigor with the increase seed and fruits storage period. The fruit storage for 10 days and seeds storage for 120 days allowed hither seeds germination.
