The objective was to determine the effect of four shade levels of on Oreopanax floribundum germination. Under greenhouse, the fruits were placed in sealed plastic bags for 48 hours; they were scarified in river sand and immersed in water for 12hours.Then, they were left on newspaper for two days, in trays with a substrate consisting of organic matter (40%), peat(20%), river sand (20%) and perlite(20%). Four levels of shadow were managed: 90%, 65 %, 33% and control. A positive effect was obtained with use of polyshade in the percentage and speed of seed germination. With polyshade of 90 % was reached a daily germination of 18 % during the first two days, whereas under the polyshade of 65 % and 33 % the germination was 17 %, and 14 %, during 7 and 9 days, respectively. For 39 days of duration of the test under effect of polyshade the total of germinated seeds was between 69 and 70 % and without polyshade in 30 %.
