The effects of bacteria attacks on the permeability and drying characteristics of sugi wood were confirmed by subjecting the wood to natural ponding. After the ponding for 6 months the moisture content of sugi log increased higher than 150% not only in the sapwood but also in the heartwood. The bacteria were observed around the pit apertures and on the pit membranes in tracheids or in ray parenchyma cells by SEM. Most of the encrusting substances adhering to the cell lumens and the pit chambers were removed. It suggested that the permeability of the sugi wood would be improved by the ponding. The longer the ponding the faster the drying rate. The improved drying characteristics were observed not only in the red heartwood but also in the black heartwood of sugi wood. The characteristics of strength were not decreased even after 18 months ponding

通过对水杉木材进行自然积水处理，研究了细菌对水杉木材渗透性和干燥特性的影响。经6个月的积水处理后，无论是边材还是心材的含水率都增加了150%以上。扫描电镜观察发现，细菌分布在纹孔周围、纹孔膜上、管胞内或射线薄壁细胞内。附着在细胞腔和纹孔室上的大部分结壳物质被去除。这表明，水杉木材的渗透性将通过积水得到改善。积水时间越长，干燥速度越快。无论是红杉心材还是黑杉心材，干燥特性都得到了改善。即使在18个月的积水后，强度特性也没有下降
