Equations for calculation of volume and weight of aerial compartiments of eight-year-old Grevillea robusta (Cunn.) trees PFB - Pesquisa Florestal Brasileira
Ferreira, Carlos Alberto; Martins, Emerson Gonçalves; Silva, Helton Damin da.
This paper presents results obtained for fitting equations to estimate volume and weight of aerial compartments of Grevillea robusta trees. Twelve trees representing four provenances were collected from an eight-year-old provenance trial located in the municipality of Anhembi, State of São Paulo. The trunks of the trees were segmented until the minimum diameter of 5 cm. The heartwood was measured till the height it was possible to be distinguished in the tree. Allometric models were the most suitable for this paper proposes. The inclusion of the combined variable (total height multiplied by the diameter at breast height) contributed to a better adjustment of most equations. The standard errors of the estimates were relatively high for heartwood and bark...
