Resumo

Summary The high commercial value of mahogany, Swietenia macrophylla King, its native occurrence in Amazonia which permits its exploitation, the absence of silvicultural research, and the different opinios of various authors are the motivations for this work. The purpose is to show its silvicultural characteristics for the region. With botanical material (flowers, fruits and seeds) collected in Itacoatiara we were able to identify the species and perfum 5 germination tests in 13 different conditions putting to the test techniques recummended by some authors. The following were studied : The type of seed with regard to cropping, the viability of the seed when stared, the depth of sowing, the ideal soil type, the method of sowing. We made selection and tests of the power of germination a record of sowing, a daily count and we studied frequency and percentage of germination. We presente figures of geographical distribution, of the botanical material, of seedlings in 4 stages of development, and plates and graphs of frequency and percentage for each of the tests. We comment upon and present own conclusions about the germination of the species.
