Abstract
Pleurotus djamor, also known as pink oyster mushroom, is a newly introduced exotic species of mushroom in the Philippines. Because of its color, most Filipinos are fascinated by this mushroom. In this study, the influence of corn grit decoction socrose gulaman using three varieties of corn (sweet corn, glutinous corn and yellow corn) and physical conditions (pH, aeration, illumination and temperature) on mycelial growth was evaluated. Moreover, corn based substrate saw dust were used in fruiting body production. Maximum mycelial growth was observed in both sweet corn grit decoction sucrosegulaman and yellow corn sucrose gulaman, with pH of 8.0 incubated in either sealed or unsealed; light or dark condition at room temperature. Moreover, sweet corn and yellow corn can be used as grain spawning materials. Among the different substrate formulations used in fruiting body production, 75% corn stubbles + 25% saw dust and the control registered the shortest incubation period and shortest number of days to primordial initiation were recorded in 25% corn stubbles + 75% saw dust. Among the different corn based substrate formulations, 100% corn stubbles and 75% corn stubbles+25% saw dust are the best that can use as alternative for the control. Moreover, 70% rice straw + 30% saw dust (control) exhibited the highest diameter of pileus, length of strip, weight of fruiting bodies and biological efficiency.
