The objective of this study was to determine the hypsometric relation and growth in diameter and volume of Pinus taeda L. in the city of Eneas Marques - PR. It was conducted forest inventory of the stand with 600 m² plots, totaling 15 plots. DAP was measured for all individuals and the height of 30% of the trees in each plot. Then they were cut down 16 trees, of which 8 were dominant trees and 8 average basal area diameter tree. For the determination of diameter growth and the complete volume was performed in stem analysis trees and dominant 5 5 Average basal area diameter trees. The volume for age was calculated by Smalian method. In addition, equations were adjusted to estimate the heights from the DAP and volumetric equations depending on age and depending on the diameter breast height and height. For data analysis Microsoft Excel was used and Statistical Analysis System software. To estimate the height due to the DAP, the equation that best fit was 1/√hi = 0,20641 + 1,59475 (1/di). Held in inventory was found a wooden volume available 125711,85 m³. The dominant trees had higher growth in diameter and volume compared to the average basal area diameter trees. To estimate the volume according to age the equation that best fit was In ϑ = 9,76297+4,54707.In τ-0,25226.τ. And the equation to estimate the volume depending on the diameter at breast height and height was v=0,01632+0,00004114.d^2.h. Selected mathematical models showed good fits to the data. |
