Resumo
Toe experiment was installed in Estação Experimental de Plantas Nativas do Cerrado e Exóticas Cultivadas, Universidade Federal de Goiás, situated in Porto Nacional, state ofTocantins. The seeds, object ofthis work, were caught from matrix trees placecl in the University Campus, placed in Porto Nacional, on July, 1996. From the group of seeds obtained in this way, samples of pure seeds were separated and subjected to these treatments: witness; water in air temperature during 48 hours; water at lOOºC (without giving continuity to the heating) for 24 hours; sulfuric acid (H2SO,) P.A. during 06, 10, 14, 18 and 22 minutes, using one part of acid for two parts of seeds. After the treatment with H,S04, seeds were washed with running water and revolved with glass spindle during 10 minutes and dried on paper on shadow. After these treatments, 04 replications of 25 seeds were sowed in polietilene trays, where the cells were filled with soil from the sub-earth, sterilized at 180 ºC for 20 minutes. During 30 days daily countings of the normal seedlings were effectuated. ln this period the following parameters were evaluated: growth speed, first count and emergence. Toe experimental delineatement used was entirely randomized, with 04 replications. Considering the statistic analysis from the data originated by the experiment, it was possible to conclude that from ali treatments tested, the immersion of the seeds in H S04for 22 minutes was the one that showed the greatest and the most rapid plant emergence.
