Resumen
In the occupation of Brazilian territory the forests were substituted for farming systems, being that, the southwest region of the state of the Paraná suffered intense deforestation and currently presents little forest covering and sufficiently modified. Consequently it has reduction of biodiversity in the remainders. In secondary forests degraded the enrichment in target lines to increase desirable species and to use them with planning, helping in the recovery of the forest and the income of the properties. The aim of the work was to evaluate the initial development of three planted timber species in different widths of lines in an area of Reserves Legal in initial training of development in UTFPR- DV. Before the implantation a census of the species was accomplished that were suppressed. 0x135m (control), 3x135 m and 5x135 m were installed. The experimental parcels were composed of five changes of each species and these repeated three times in the line the species (louro pardo), (pau marfim) e (peroba) was evaluated how much to the survival, growth in soil level, total height and canopy area to the two and four months of age. For measurement of the luminosity luxímetro was used the device. All species tested had high survival. Through the obtained results of the analysed variable it was possible to verify a bigger growth for the louro pardo , followed of the pau marfim and peroba. And in respect to width of the line the species had presented greater growth in the line of 5 meters, later in the line of 3 meters and finally in the line of 0 meters. It can be concluded that the louro pardo and the pau marfim had had a good development and the beginning is indicated these species for plantation of enrichment in the southwest of the Paraná, however the period of evaluation was short and is recommended the continuity of the studies.
