Taxodiomeria peizhongii is an intergeneric hybrid between Taxodium mucronatum and Cryptomeria fortunei. By more than 30 years investigation, it is found that the hybrid is well suited for the site and climate of Shanghai area, and it will be one of the main landscape trees in near few years. So it is necessary to know its basic wood properties. In this research, we harvested 6 sample trees of Taxodiomeria peizhongii and studied the elementary wood properties. The results showed that its mean annual ring width was 7.0mm, mean basic density 0.32g/cm3, and the mean percentage of latewood 24.3%. The mean treacheid length of latewood was 3.1mm, and mean treacheid width 35.1μm. Compared with other usual coniferous trees, the values of these indices were at a medium level. The period of juvenile wood was about 15 years, and the fast growing period appeared in first 10 years. The basic density, altering less in radial growth, showed a significant minus relation with annual ring width. The percentage of latewood did not related to wood density.OtherShinshu University International Symposium 2010 : Sustainable Agriculture and Environment : Asian Networks II 信州大学国際シンポジウム2010 : 持続的農業と環境 : アジアネットワークII ― アジアネットワークの発展をめざして―. 信州大学農学部, 2010, 65-70conference pape
