Abstract:samples of Eucalyptus grandis,E. saligna,E. camaldulensis and E. urophylla of 48 provenances from the experimental provenance stands in Qionghai City,Hainan Province and Changtai County,Fujian Province were collected for the test on wood structure components and wood basic density characteristics and a comparision and selection for intraspecific provenances was made. The results showed:in the two experimental plots,for the same provenance,there was no significant difference in the same plot;for the same tree species,whose wood features variances were bigger than the individual variance of the intra provenance;taking 7 features,such as fibre length,ratio of area occupied by different cells,cell wall thickness,cell walls,ratio of wall thickness to iumen diameter,ratio of cell iumen to cell diameter and wood density,which have close relation with other wood properties and uses and a comprehensive evaluation between them was made; E. grandis 14860,14849,14509, E.saligna 14429,14435,14527, E. camaldulensis 12187,15050,15062, E. urophylla 15089 from Qionghai,Hainan Province and Fujian Province were selected as the best provenances.
Keywords:eucalyptus  provenance  wood  structure  basic  density
