ABSTRACT

Pleurotus djamor is a new introduced species of mushroom in the Philippines. This paper demonstrated the utilization of corn based media for efficient mycelial growth and corn based substrate on the fruiting body production of this mushroom. The maximum mycelial growth was observed in both sweet corn grit decoction sucrose gelatin and yellow corn sucrose gelatin, with pH of 8.0 incubated in sealed or unsealed; light or dark condition at room temperature (29°C). Moreover, sweet corn and yellow corn can be used as grain spawning materials. Among the different substrate formulations evaluated in fruiting body production, 75% corn stalk and leaves 25% sawdust registered the shortest incubation period and number of days to primordial initiation. The longest incubation period and period to primordial initiation were recorded in 25% corn stalks and leaves 75% sawdust. Among corn based formulation, 100% corn stalks and leaves produced the highest yield and biological efficiency but significantly comparable to 75% corn stalks and leaves 25% sawdust. However, 70% rice straw 30% sawdust (control) exhibited the highest diameter of pileus, length of stipe, weight of fruiting bodies and biological efficiency. Keywords: corn stalks and leaves; pink oyster mushroom; biomass; corn grit sucrose gulaman
