ABSTRACT
In this paper there were studied the growth and yield of monoclonal thinned stands of Eucalyptus saligna Smith, in the southeastern region of Rio Grande do Sul state. An experiment in randomized blocks was analyzed, initiated at the age of 60 months and measured annually up to 135 months, with 5 treatments and three replication. The behavior of the control treatment, without thinning, and the treatments with maintenance of relative spacing indexes of 16, 23, 28 and 33% indicates influence in growth and yield, being obtained the dendrometric parameters. The results indicate the maintenance of indexes of relative spacing between 16 and 23%, since these cause less loss in total production and significant increment in average diameter (DBH).
