Potential of seed germination of orelha de macaco was evaluated after storage at environment and pre-germinative treatments and initial growth of seedlings under shade. Seeds were stored at environment temperature during 5, 8 and 12 months, and right after, they received the following scarification + imbibition treatments: 1) H2SO4 for 5 minutes; 2) H2SO4 for 5 minutes + water for 24 hours; 3) H2SO4 for 5 minutes + GA 200 mg L-1 for 24 hours; 4) H2SO4 for 5 minutes + KNO3 1% for 24 hours; 5) H2SO4 for 10 minutes; 6) H2SO4 for 10 minutes + water for 24 hours; 7) H2SO4 for 10 minutes + GA 200 mg L-1 for 24 hours; 8) control. Sowing was done in Germination chamber at 20/30ºC darkness/light. The experiment was carried out in DIC in 3 x 9 factorial scheme with four replications of 20 seeds. Seedlings were kept under 30% and 50% of shade and under plain sun. Seeds can be stored until 12 months reaching high percentage of germination when they were scarified for 5 or 10 minutes without the need of pre-imbibition. Under 30% of shadow, seedlings showed higher AF, MST, MFF, PA/R. Cultivation in plain sun must not be recommended for formation of orelha de macaco seedlings
