Research on the Growth Performance of Eucalyptus maculata Provenances

The results of 6-year growth monitoring to a trial of 8 Eucalyptus maculata provenances indicated differences statistically existed among the tested provenances in survival rate,DBH,height, volume and biomass yields.The provenance 6169 from Queensland has the best performance with high survival rate and good growth performance(the volume and biomass is 3.1 times of that of the worst provenance 15361).The performance of provenances 13569 and 13542 are also good.The results also showed a correlation between the survival rate and the altitude and longitude of the provenances.This trial was established in poor hilly land.The results of the experiment provided useful information for provenance selection in the regions with similar site condition.
