Bamboo is so easily Mouldy that bamboo products have no high value added utilization. Therefore, the effect of red extractives from 18 plantation woods on bamboo biology moulding was studied based on full-factor test. The results were: (1) The red extractives of plantation could mostly inhibit the growth of Penicillium expansum, but a few could inhibit the growth of Aspergillus niger. (2) The red extractives of Cunninghamia lanceolata bark and shavings, Deodar cedar branch, Eucalyptus dunnii bark, Eucalyptus tereticornis bark, Bagasse, Eucalyptus camaldulensis branch and shaving were the most effective in controlling spore germination of Penicillium expansum, and the one raphiolepsis branch was the most effective in controlling spore germination of Aspergillus niger. (3) The effect of the red extractives from Cunninghamia lanceolata bark and shaving, Deodar cedar branch, cypress branch, Eucalyptus tereticornis branch on bamboo moulding was highly remarkable on outdoor test. So the plantation woods could be used as biologic mould inhibitor for bamboo.
