Caryocar brasiliense is a native species from Brazilian cerrado that has a considerable economic potential. The aim ofthis work was verifying the effect of substances with potential for seed germination stimulation. Seeds were extracted from theendocarps and set to germinate in paper rolls moistened with the following solutions: distilled water (Control); 2mmol L-1 KNO3(Nitrate); 2mmol L-1 Etephon (ET); 1mmol L-1 GA3 (GA), 1mmol L-1 GA3 + 2mmol L-1 Etephon (GA + ET). The germination and thegermination mean time were, respectively, 54.0% and 9.3 days in the GA treatment, 47.3% and 11.0 days in the GA + ET treatment,32.0% and 12.2 days in the Control treatment, 30.7% and 13.1 days in the Etephon treatment, and 20.1% and 13.1 days in the Nitratetreatment. Low germination rates were observed in the GA + ET treatment up to the ninth day from sowing, when compared to the GAtreatment, what indicates a possible seed germination inhibition due to ethylene presence. |
