Atmospheric conditions in a disused rail road tunnel were surveyed, and then several vegetables such as potato (Solanum tuberosum L., cv. Toyoshiro and Norin-ichigo), Chinese yam (Dioscorea opposita Thunb. cv. Nagaimo) and burdock (Arctium Rappa L.) were stored in the tunnel for about three months.The results are summarized as follows:(1) An yearly average temperature was about 7°C at several locations ranging 100m to 500m from the tunnel entrance, and the humidity was kept at about 95%.(2) Reducing sugar content of potato tubers increased gradually during tunnel storage, while its weight loss was only 1% after 3 months of the storage.(3) Although the viscosity of Chinese yam tubers slightly increased at a beginning of storage, after that it showed gradual decrease.(4) When the humidity in a tunnel is kept at 95% or more, it will be effective to store the burdock without polyethylene film.
