RESUMO:

The aim of this work was to evaluate the influence of the edaphoclimatic variables on the basic density (DB) and the mean annual increment (IMA) of eucalyptus wood. three clones were planted at 10 growth sites, distributed in the five regions of brazil, at 4 years of age. the variables precipitation, temperature, vapor pressure deficit and water storage capacity in the period from 2012 to 2015 were considered. the techniques of canonical correlation, main components and cluster analysis were performed, in order to verify if there were influences of each edaphoclimatic variable on the set of production variables (DB and IMA), and also, formation of groups similar to each other. the precipitation was positively correlated with the production variable, whereas the temperature and the vapor pressure deficit correlated negatively. the capacity of water storage in the soil does not contribute to the relation of the set of edaphoclimatic variables on the production variables. clones E5 and G7 were more sensitive to climatic variations at different sites than clone P7. it is concluded that the responses of the wood to the DB and the IMA are clone-specific and the average annual increment of the wood changes in a greater proportion than the basic density in front of the environmental variations.
