Resumo: | This paper deals with the prognosis of the individual volumetric growth of Eucalyptus species in the Brazilian South Region. It was accomplished in a fertilizer trial with Eucalyptus dunnii and a competition trial among species (E. bicostata, E. “cambiju” - natural hybrid, E. deanei and E. viminalis) implanted in Vila Velha, PR. The method of successive regressions, modified to the exponential form, including the volume at three years of age and survival was applied. The results gave evidence of acceptable efficiency of the method to estimate individual volumetric growth of the trees of the stands, especially for E. deanei and E. dunnii, species well adapted to the region. However, species with low growth potential, for example E. bicostata, presented low individual and stand volumes at the end of the rotation, despite its high survival. It was necessary to include survival in the model, for better accuracy for E. “cambiju” with decreasing survival along the rotation. |

A prognose do crescimento volumétrico individual foi realizada com dados de um ensaio de adubação de Eucalyptus dunnii e de competição de espécies incluindo E. bicostata, E. “cambiju” (híbrido natural), E. deanei e E. viminalis, implantados em Vila Velha, Ponta Grossa, Paraná. Utilizou-se para este estudo o método das regressões sucessivas modificado para a forma exponencial, incluindo como constante o volume aos três anos de idade. Os coeficientes de correlação obtidos, os erros padrão das estimativas e a distribuição de resíduos, para os modelos propostos no presente estudo, demonstraram a possibilidade do uso do método das regressões sucessivas, modificado para a forma exponencial, com a inclusão do volume na idade base de três anos, e a expectativa de sobrevivência ao longo da rotação, para a prognose de volumes individuais de árvores de espécies de Eucalyptus. A precisão da prognose é alta para espécies bem adaptadas, que apresentem sobrevivência elevada, até o final da rotação por exemplo E.deanei e E. dunnii. O E. “cambiju” apresentou acentuado decréscimo de sobrevivência ao longo da rotação. Neste caso, para maior precisão, foi necessário a inclusão no modelo do valor da recíproca da sobrevivência. Populações com baixo potencial de crescimento, apresentam volumes individuais e populacionais baixos, mesmo com alta sobrevivência. O E. viminalis e o E. cambiju, ambos com baixa sobrevivência ao final da rotação, apresentaram volumes individuais mais elevados que as outras espécies, em idades mais elevadas, exceto E. dunnii.
