| Abstract: |
| The different diameter classes logs of clones plantations of Eucalyptus.grandis×Urophylla was measured and studied in this paper, along with the total logs of plantations and the average diameter at breast height , Different diameter classes logs of the plantations can be easily calculated by the ratio of Different diameter classes of logs of the plantations. |
| Key words: Eucalyptus.grandis×Urophylla plantations Different diameter classes logs ratio |
