Abstract
Eucalyptus as fast growing tree with a great potential of coppicing at consecutive periods is the most suitable tree species to provide wood at short period. Produced woods under short rotation system is used in different industries such as particle board, pulp and paper. This research was conducted to compare coppicing potential of different eucalypt species and Provenance in Pars-Abad region of Ardabil Province. For this purpose six provenance of Eucalyptus, including E. camaldulensis 41-ch, E. grandis 156-ch, E. macarthurii 169-sh, E.saligna 171-ch, E. viminalis-168-ch and E. viminalis168-sh were planted, based on statistical design of Randomized Complete Blocks, with three replication at 3x3 meter spacing and 49 seedlings per plot. The seedlings were cut after one year growth and some parameters such as number of shoot, and shoot height and diameter were measured. The results showed that, there was significant difference between the eucalypt species and provenances in respect to eucalypt characteristics The greatest number of shoots belonged to E. viminalis 168-sh and the greatest value of shoot height and diameter belonged to E. camaldulensis 41-ch. According to cluster analysis result, E. camaldulensis 41-ch, E. grandis 156-ch and E. viminalis 168-sh are suggested for short rotation system.
