Resumo
The use of quality seedlings is important to the successful implementation of the cultivation of
papaya. However, the presence of sarcotesta in seed dormancy and post-harvest fruit can harm
the seedling production on a commercial scale. This way, in-house vegetation, was evaluated in
the emergence and development of papaya seedlings the effects of combination of fruit ripening
stage and physical methods of removing the sarcotesta. Adopted the completely randomized
design, in factorial 2 x 4, with two stages of maturation (3 or 5) and four methods of extraction of the
sarcotesta (witness, pressure on sieve under running water, friction in coarse sand or smear with thick
plastic bristle brush). The maturation stage 3 was the most suitable for the extraction of seeds for the
production of seedlings. The presence of the sarcotesta negatively affected the percentage and
the emergency speed index, and root growth. The pressure in sieve under running water, rubbing
with coarse sand and smear brush with plastic bristles are suitable methods for removal of sarcotesta
of papaya seeds.
