Abstract:

The paper inverstigated the effect of intermittent flood upon the wood physical and mechanical properties of Taxarlium ascendens.The results are as follows:Annual rings width、latewood percentage、shrinkang、basic specific gravity and main mechanical properties of Taxodium ascendens wood under intermittent flood are smaller than those of wood without intermittent flood, but shrinkage differences of wood is bigger than that.The T-test valves indicated that there no significant differences between wood under intermittent flood and without intermittent flood in annual rings width and shrinkage differences.there are significant variances in other physical and mechanical properties.

Key words: Intermittent flood, Taxodium ascendens, Physical and mechanical properties
