Abstract
In the case of the single inoculation with Graphostroma platystoma to the branch segments, stromata were formed between 15-35℃, and the rate of stroma formation increased in proportion to the temperature between 15℃ and 30℃. The optimum stroma formation was at 30℃. In the case of the simultaneous inoculation with G. platystoma and Lentinula edodes, the rate of stroma formation and the rate of sectional occupation were high at 30℃ but were remarkably low at 25℃ and below. The water content of the branch segments was adjusted between 21% and 47% by adding water to the container and immersing the branch segments into water. In the case of single inoculation with G. platystoma, stromata were formed under a water content of 21% and above, and the rate of stroma formation was highest around 30%. In the case of simultaneous inoculation with both fungi, both the rate of stroma formation and sectional occupation were the highest at 21%, and decreased in inverse proportion to the water content of the branch segments. Between 10℃ and 30℃, L. edodes invaded the areas which G. platystoma was occupying and replaced it. L. edodes invaded these areas rapidly between 15-25℃ but rather slowly at 10℃ and 30℃.
