Assessment of Grain Extract Media on Mycelial Growth of Pleurotus spp. (P. Sapidus and P. Flabellatus)

Abstract

The aim of present investigation pertains to study the impact of different culture media on the mycelial growth and dry weight of Pleurotus spp. Grains generally contains high nutritional content thereby decreases the harvesting period of mycelium and enhances dry weight. The study was conducted at Mushroom Laboratory Department Plant Pathology, S. V. P. University of Agriculture and Technology, Meerut, UP, India. Different crop grains were used as source of nutrition for fungus and added in PDA (media) in separate amount. Experiment was conducted in seven treatments with four replications. All the extracts observed varied mycelial growth of Pleurotus spp. After nine days maximum radial growth (90.00 mm) in both species (P. sapidus and P. flabellatus) was observed in barley extract media. The maximum growth rate (10.00 mm/day) of mycelium in P. sapidus and P. flabellatus was recorded in barley extract agar. Maximum dry mycelium weight (7.98 mg/100 ml & 8.35 mg/100 ml) of P. sapidus and P. flabellatus was observed in barley extract broth, respectively.
