Failure of seed germination and subsequent seedling growth is a major cause of yield decrease for papaya (C.papaya) due to a rapid decay of seed capacities. Papaya growers normally deposit six or up to twelve seeds per germination container, which increases production costs (Vargas, 1996). The fast reduction in seed germinability capacity observed in this seed has been correlated with the presence of inhibitors of germination in both the testa and sarcotesta (Paz and Vázquez, 1998). The activity of seed inhibitors has been reduced by soaking and washing the seed in water (Vargas, 1996) or by sun drying (Wood et al., 2000). Papaya seed conditioned in the presence of gibberellic acid improved its germination, but, after drying, a decrease in seed vigor and germination was shown by the conditioned seed (Marcos and Maleus, 2008).
