Comparison of growth rate of four pleurotus fungi species on wheat straw and date palm leaf substrates

A. Kabirifard A., . and Fazaeli H., . and Kafilzadeh F., . Comparison of growth rate of four pleurotus fungi species on wheat straw and date palm leaf substrates. pp. 55-63.

In a 43 factorial completely randomized experiment four Pleurotus species of cultures namely P. florida P. ostreatus A. P. ostreatus M. and P. ostreatus T. were cultured on wheat straw (WS) date palm leaves (DPL) and potato dextrose agar (PDA) substrates. Growth rate of the mycelium was measured for two weeks of incubation. At the end of second week all plates were removed from the incubator and the biomass was dried and analyzed. During the first week of fermentation growth rate of P. ostreatus A. and P. ostreatus M. were significantly higher (P0.05) than P. florida and P. ostreatus T. whereas it was inverse during the second week of incubation. A significant interaction effect (P0.05) was found between cultures with substrates. During the first week of incubation the highest amount of mycelial growth rate was shown by P. ostreatus A. and P. ostreatus T. on PDA followed by P. florida. In addition P. ostreatus A. and P. ostreatus T. had significantly higher growth rate (p0.05) on DPL than WS. However at the end of second week the cumulative growth rate was not significantly different among the cultures or the substrates. Regarding the dry mater (DM) and organic mater (OM) losses significant differences (P0.05) were found between the substrates after two weeks of fermentation but no significant variation was shown among the cultures. However there was a significant interaction effect (P0.05) of cultures with substrates for DM and OM losses. Crude protein (CP) content was significantly different (p0.05) among the cultures on the different substrates

Abstract

In a 43 factorial completely randomized experiment four Pleurotus species of cultures namely P. florida P. ostreatus A. P. ostreatus M. and P. ostreatus T. were cultured on wheat straw (WS) date palm leaves (DPL) and potato dextrose agar (PDA) substrates. Growth rate of the mycelium was measured for two weeks of incubation. At the end of second week all plates were removed from the incubator and the biomass was dried and analyzed. During the first week of fermentation growth rate of P. ostreatus A. and P. ostreatus M. were significantly higher (P0.05) than P. florida and P. ostreatus T. whereas it was inverse during the second week of incubation. A significant interaction effect (P0.05) was found between cultures with substrates. During the first week of incubation the highest amount of mycelial growth rate was shown by P. ostreatus A. and P. ostreatus T. on PDA followed by P. florida. In addition P. ostreatus A. and P. ostreatus T. had significantly higher growth rate (p0.05) on DPL than WS. However at the end of second week the cumulative growth rate was not significantly different among the cultures or the substrates. Regarding the dry mater (DM) and organic mater (OM) losses significant differences (P0.05) were found between the substrates after two weeks of fermentation but no significant variation was shown among the cultures. However there was a significant interaction effect (P0.05) of cultures with substrates for DM and OM losses. Crude protein (CP) content was significantly different (p0.05) among the cultures on the different substrates
