Classifica??o de clones de Eucalyptus sp visando à produ??o de polpa celulósica

摘要

The objectives of this study were to classify and select clones of Eucalyptus sp, aiming at pulp quality improvement. The clones were classified according to the screened yield, pulp viscosity and active alkali used for pulping. Classification of the clones was achieved by cluster analysis using the Tocher method. The clones were classified in groups having high, medium and low potential for pulp production. The results showed that the parameter that most contributed to group the different Eucalyptus sp clones was the screened yield (58,1%), followed by pulp viscosity (35,0%). In general, large variation was observed for the parameters evaluated.
