Results from an experimental research on germination of Vriesa incurvata Gaudich. carried out in Rio da Onca State Park (Matinhos-PR- Brasil, October -December/2003) are presented. With the goal of producing seedlings of this species, the experiment was conducted in a natural environment under forest canopy on substrates of low cost and easy accessibility for rural producers, seeking to reproduce the situation and infrastructure available to coastal communities involved in the extraction of this species. We tested the following materials: pine bark, pine bark recalcitrant, coconut fiber and forest litter. The xaxim fiber was used as control group. The experiment was randomly delineated in 4 blocks with 5 treatments each, containing 25 seeds per experimental unity. The experiment was carried out in a natural environment under forest canopy, in plastic vases attached to the tree trunks, aiming to reproduce the environmental situation and the infrastructure available to the coast communities involved with the wild harvesting of this species. Germination and survival of plants were weekly evaluated during 58 days after sowing. The alternative substitute substrate with best performance was the pine bark, due to the germinability (32 ± 11,67%) and survival (100%) rates significantly similar to those obtained with xaxim fiber, (contrlol group) (40,50 ± 12,87%; 100 % - Tukey Test, p<0.05).
