Resumo. ABSTRACT The Brazilian industry commonly dries different species of eucalypt in a same load because of the difficulty of identifying the species, hybrids and clones, and also by optimizing the use of the kiln. However, this practice is not recommended in the literature. The aim of this work was to verify the quality of grouped conventional drying of Eucalyptus saligna , Eucalyptus grandis and Eucalyptus dunnii from clonal plantations. To this end, three loads were dried with the three species together in a pilot conventional dry kiln. The criteria used to analyze the quality of dried wood were final moisture content, end checks, cupping, collapse, moisture gradient and drying stresses. Eucalyptus grandis showed the best quality of drying, followed by Eucalyptus saligna , and both species have potential to be kiln dried together. Eucalyptus dunnii had the worst quality of drying, and should not be kiln dried together with Eucalyptus grandis and Eucalyptus saligna. The basic density and shrinkage were good parameters for the expected quality of the drying of eucalyptus species, in which less dense and more dimensionally stable species had better quality of drying. The drying schedule used must be modified to further drying of these species, especially regarding to uniformity and conditioning periods, which were considered insufficient.
