摘要
在海南省琼海市，中国林业科学研究院热带林业研究所按树种源试验林内，采集了巨桉、柳桉、赤按和尾叶桉４４个种源的木材试材。对木材解剖分子和基本密度进行了研究和评优。从中选出巨桉１４８６０、１４８４９、１４５０９；柳桉１４４２９、１４４３５、１４５２７；赤桉１２１８７、１５０５０、１５０６２和尾叶桉１５０８９为最优种源。
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.
