Growth characteristics of oyster mushroom following the addition of wheat straw pellet as a substitute for beet pulp

영어: The present study investigated the optimum additive ratio of wheat straw pellet as a substitute for beet pulp during oyster mushroom cultivation. The chemical properties across treatments were pH of 4.8–5.5, total carbon content of 45.9–46.5%, total nitrogen content of 1.5–1.7%, and carbon-to-nitrogen ratio of 27.8–31.0. Mycelial growth was the fastest in a medium containing 20% wheat straw pellet (at 88.2 mm in ‘Heuktari’ and 70.3–79.6 mm in ‘Suhan-1Ho’); however, there were no significant differences in mycelial density among the treatments. The characteristics of fruiting bodies by variety were as follows. In ‘Heuktari’, the valid stipe number per bottle (1,100 cc) was 22.5 and yield was 177.1 g/1,100 cc in the mixed medium containing 10% wheat straw pellet, with the values being comparable to those of controls. In ‘Suhan-1Ho’, the valid stipe number per bottle (1,100 cc) was 14.0 and yield was 151.2 g/1,100 cc in the mixed medium containing 10% wheat straw pellet, with the values being comparable to those of controls.
