Influence on Uniform Primordia Formation of Pleurotus ostreatus by Post-incubation Period and Temperature

In this experiment, we aim to investigate the effects of 3 kinds post incubation period conditions during incubation on uniform primordia formation and cultural characteristics of oyster mushroom(Pleurotus ostreatus). 3 kinds post incubation period 35, 40, 45days and control were treated for 30 days. 2 kinds incubation room temperature 23°C, 26°C and control were treated 20°C. The substrate temperature of Suhan No. 1 and Gonji No. 7, oyster mushroom varieties, were tend to increase 24°C`27°C at 11`14days after inoculation and then maintained in treatment temperature during post incubation period. The longer post incubation days and the higher post incubation temperature of room were lower side primordia formation of two cultivars. However, the higher post incubation temperature of room resulted in the higher percentage of primordia formation of two cultivars. In addition, the yields were the highest and non-product ratio of fruit body in 35`40day, 23°C of post incubation conditions were the lowest than other treatments.
