Mycelial Growth of Pink Oyster Mushroom (Pleurotus djamour) on Banana Sucrose Gulaman and Fruiting Body Production on Banana-Based Substrate Formulations

Abstract

This study evaluated the mycelial growth of Pleurotus djamour on banana sucrose gulaman and fruiting body production on banana-based substrate formulations. Fruits of three local banana varieties, namely lakatan, latundan, and saba were used in the preparation of culture media. The mycelial growth and mycelial density were determined. Moreover, different banana-based substrate formulations such as 100% banana leaves, 75% banana leaves + 25% sawdust, 50% banana leaves + 50% sawdust, 25% banana leaves + 75% sawdust,  and 100% sawdust were evaluated. The rice straw-based substrate formulation consisting of 70% rice straw and 30% sawdust was used as the control. Saba sucrose gulaman exhibited faster mycelial growth (11.79mm / day) and thick mycelial density. On the other hand, potato dextrose agar (control) recorded the smallest mycelial growth (9.33 mm / day) and very thick mycelial density. Among the different substrate formulations, 70% rice straw + 30% sawdust (control) exhibited shorter incubation period (26.73 days) and shorter duration of primordial formation (28.93days). However, 50% banana leaves + 50% sawdust exhibited highest yield (136.51 g) and highest biological efficiency (19.50%).
