Abstract
Cauliflower mushroom ($Sparassis$ $crispa$) is being cultivated as a functional mushroom since the mushroom contains larger amount of ${\beta}$-glucan than other edible or medicinal mushrooms. In this study, as a fundamental study for the cultivation process of cauliflower mushroom, we assayed the mycelial growth and the productivity of the mushroom cultivated on the sawdust-based medium made of larch ($Larix$ $kaempferi$) by 4 kinds of medium densities and 6 kinds of particle sizes. Low densities of sawdust-based media (0.68~0.72 g/$cm^3$) showed high variations in mycelial growth at early stage on sawdust-based medium. The coefficient of variance for the mycelial growth decreased from higher than 40% at the 3rd week to lower than 10% at the 7th week. High density of sawdust-based medium (0.80 g/$cm^3$) showed relatively lower variation in the mycelial growth at early stage with less than 30% of coefficient of variance, the high density of sawdust-based medium was thought to be quite stable compared to the lower densities of sawdust-based medium. From the viewpoint of mushroom productivity especially for the goods (excluding bottom of fruiting body), 0.76 g/$cm^3$ was better than any other densities; the return rates of fruiting body from each medium were 12.2, 13.6, 13.1, and 12.0% for 0.80, 0.76, 0.72, and 0.68 g/$cm^3$, respectively. By the way, it took about 40 days for harvesting from primordium formation with the sawdust-based medium excluded the particles less than 1 mm, while it took about 70 days with the medium including the particles less than 1 mm. The yield from the sawdust-based medium with the particles less than 1 mm was also quite less than any other sawdust-based medium especially for the goods. Therefore, we recommend that the sawdust-based medium with larch for the cultivation of cauliflower mushroom be prepared as 0.76 g/$cm^3$ in medium density with excluding the particles less than 1 mm.
