Abstract

In this study, mould resistance of the bamboo species Thy-rostachys siamensis treated with chitosan was tested underlaboratory and praxis condition. In the laboratory experiment, bamboo specimens were treated with various solutions of bothlow molecular weight chitosan (LMW) and medium molecularweight chitosan (MMW) at concentrations of 1, 2 and 3% andChitosan-copper complexes (CC) at concentrations of 2, 4 and 6%. Mould growth on the specimens was evaluated 1, 2, 4 and 8 weeks after they were exposed to the inoculation with a conidia mixture of six moulds isolated from bamboos. In field test, bamboo samples were treated with the effective formulations from the laboratory experiment. Evaluation of mould growth on the samples was done 1, 2, 4 and 8 weeks after exposure at the storage site of Bamboo company, Binh Duong. The results showed that treatments with chitosan (MMW) at the concentration of more than or equal to 3% and Chitosan-copper complexes at the concentration of more than or equal to 4% completely inhibited mould growth on the bamboo T. siamensis.
