Abstract
The mycelial and fruiting body performance of Thai and Japanese strains of Pleurotus sajorcaju were compared on two formulated substrates. Evaluation was based on incubation period of inoculated bags, number of days from complete mycelial colonization to primordial formation, number of days from opening the bags to first harvest, number of fruiting bodies per bag, average weight of individual fruiting bodies, total yield of fruiting bodies, diameter of individual pileus, length of stipe and biological efficiency. The Thai strain had a significantly shorter incubation period but longer number of days before primordia appeared. The Japanese strain yielded significantly higher yield and biological efficiency than the Thai strain. Pleurotus sajor-caju grown on Volvariella volvacea spent mushroom compost had a significantly faster incubation period, lesser number of days from complete mycelial colonization to primordial formation, higher yield and biological efficiency. Those grown in composted rice straw had a longer incubation period, took longer for complete mycelial colonization to primordial formation, and a lower yield and biological efficiency.
