This experiment is merely a continuation of the preceding one, in which the test on the prevention of mildew on bamboo stems with Na-PCP solution in a concentration of 7/1000 was carried out.1) Immediately after bamboo stems were dried in a vessel to a moisture content of about 4.9% at 95℃ and reduced pressure (50 mmHg) for 60 minutes, a Na-PCP solution was introduced to it under reduced pressure. The Na-PCP solution impregnated perfectly into bamboo tissues within 15 minutes when they were kept there under a pressuer of 5 kg/cm^2.2) The concentraiton of Na-PCP in a unit volume of its solution decreased with the number of times of introducing it under pressure, and it was found to be necessary to regulate the available concentration of Na-PCP in the solution.3) Except the spraying with conidial suspensions on the inner part of section of the bamboo stem treated with the preservative, both the direct inoculation of conidia and the spraying with conidial suspensions on the stem inhibited the growth of molds.Therefore, it is possible to preserve bamboo stems for a long period of time by treating them with the preservative.
