| This study aimed to estimate the height of the diameter at breast height by adjusting mathematical equations in a Pinus taeda L. population in the municipality of Eneas Marques, PR. For this, we conducted a forest inventory through systematic sampling. In each plot was carried out to measure the circumference at breast height of all individuals , and the overall height of only 30 % of them , and other times estimated by the chosen equation. To adjust the hypsometric models was used PROC REG procedure , where ten mathematical models were tested . Of these models were selected that showed the best results of the adjusted determination coefficient, coefficient of variation , calculated F , standard error of the estimate and graphical analysis of waste. Best... |

| Due to the increasing need for forest roads, parks and gardens with good quality seedlings, the study aimed to evaluate the initial development of seedlings of Bauhinia variegata L. and Ceiba speciosa (A. St. Hil.) Ravenna in different proportions bed aviary on the substrate. To this end, it tested five substrates made from bed aviary: T1: commercial substrate (CS) control, T2: 33.3% of soil (S), 33.3% sand (SA) and 33.3 % Bed aviary (BA); T3: 25% S, 25% SA, 50% BA; T4: 16,6% S, 16,6% SA, 66,6% BA; T5: 100% BA. From the results, it is concluded that all substrates studied were shown to be suitable for the development of seedlings of B. variegata and C. speciosa, however, the use of bed aviary becomes interesting in the production of seedlings, therefore,... |
