Resumo
Papaya is one of the most consumed tropical fruits in the world. The seedling production on a commercial scale is affec-
ted by problems in seed dormancy due to sarcotesta and postharvest. Thus, in a greenhouse, we evaluated the effects
of combining the maturity stage of fruits and temperature of soaking in water, the emergence and seedling growth of
papaya. We adopted a completely randomized design in a factorial 2 x 4, two ripening stages (3 and 5) and four tempe-
ratures soaking the seeds in water (25 °C, 50 °C, 75 °C and 95 °C). Seeds from fruits at ripening stage 3 provided higher
percentages and speed, mass and seedling fresh matter that at the stage 5. Higher temperatures were more efficient for
promoting changes in the structure and composition of the sarcotesta without harming the embryo and, consequently,
the emergence of seedlings. Seeds from fruits at ripening stage 3 soaked in water the temperature of 95 °C are suitable
for the production of seedlings.
