Abstract:
The white button mushroom, Agaricus bisporus is commercially the fifth important edible mushroom, accounting for a Korean production of 11,493 tons in Korea, 2014. The button mushroom mostly cultivated at mushroom farm controlled 16-19°C temperature during fruiting period in all seasons. For this reason, the production costs including the cost of energy, is very expensive to keep optimal cultivation temperature. In this study, strains collected from various countries were investigated on the mycelial growth at different incubation temperature and cultivated at different growth temperature conditions to use baseline data to develop high temperature-tolerant varieties. Mycelial growths of the strains were measured after incubation in CDA (Compost Dextrose Agar) during two weeks. 12 strains among total 197 strains were divided into 3 groups. Strains incubated well in low temperature (15, 20°C) as A group, high temperature (25, 30°C) as B group and all incubation temperature (15, 20, 25, 30°C) as C group. These strains cultivated in 16°C and 25°C temperature to confirm relationship between mycelial growth and morphogenesis of fruiting bodies in different temperature. As this cultivation results, strains including A group was 6 days faster than those including C group at fruiting formation in high growth temperature (p<0.05). We will analyze genes related to incubation, growth temperature and fruiting formation with mycelial and fruiting bodies.
