1) The relation between the growth of molds and yeasts, singly or together, and the hygroscopicity of bamboo-stems was investigated.2) The growth at a temperature of 30℃.a) The substrates, which had a hygroscopicity below about 11.7% and contained 12.2% of moisture, permitted no growth of all the molds at a relative humidity of 75%.b) All the molds except Asp. niger and Pen. citrinum could not grow on the substrates which had a hygroscopicity of about 12.5% and contained 13.0% of moisture, when the relative humidity was 80%.c) All the molds could readily grow, when the hygroscopicity of substrates increased in accordance with the relative humidity which had risen to 85〜90%.3) In case of the coexistence of molds and yeasts, the former grew luxiriantly and damaged the substrates, but the latter hardly grew on them and produced no stain.
