Abstract

This research evaluated the behavior of clone seedlings of natural hybrid of Eucalyptus camaldulensis Dehnh-Eucalyptus urophila S. T. Blake, identified as  clones 8, 9, 11, and 12. Eucalyptus species/provenance were: APS-V (Eucalyptus camaldulensis, Zimbabue – Africa provenance), USA (Eucalyptus urophylla, Avaré, Brazil provenance), EpK (Eucalyptus pellita Kuranda, Australia provenance) and EcP (Eucalyptus camaldulensis, Petford, Autrália  provenance). The Experiment was established in four planting spacing (3x2m; 6x2m; 6x3m and 6x4m). The experimental design was the entirely casualized block in a factorial outline (8x4x3), with eight genetic materials (four clones and four species/provenances), four spacing and three repetitions totaling 96 parcels. The collection of data was accomplished at 9.4 years of age. The survival, DAP, was evaluated the total height, the individual volume and for hectare. The obtained data were submitted to the of Scott-Knott average test at 5% of probability. The results showed that, for DBH and volume per plant the interaction clones/provenance x spacing was significant; the volume per hectare decreased as the spacing increased; the height  was not affected by spacing, but was affected by the genetic material; for survival, the interaction clones/provenances x spacing was significant.
