Abstract

The durability of bamboo based on its chemical and mechanical properties is a crucial consideration for the wood-based industry due to its vulnerability to insects and microorganisms. We investigated the dynamic changes of chemical and mechanical properties of Phyllostachys edulis under air-dry and water storage conditions for 3, 6 and 12 months respectively. The chemical properties of P. edulis bamboo culms varied with culm age but insignificantly with culm height. The mechanical properties of P. edulis culms showed an increasing trend with culm age. Water storage condition decreased the ash, SiO2 and lignin content, but increased the ethanol-benzene extracts. It also created an anaerobic environment for bamboo culms in which only anaerobic respiration was possible contributing to reducing the content of soluble sugar and starch, thereby beneficial for decreasing the damage from insects and microorganisms. Moreover, the water storage conditions could maintain culm mechanical performance better. Therefore, the indigenous practice of local people to store bamboo culms in ponds has good science behind it and water storage practices of bamboo culms was recommended.
