Comparative Growth Characteristics and Yield Attributes of Lingzhi or Reishi Medicinal Mushroom, Ganoderma lucidum (Higher Basidiomycetes) on Different Substrates in India

Abstract

The present study investigated the effects of four forestry byproducts (sawdust of oak, mango, khair, and tuni) and three agricultural residues (paddy straw, wheat straw, and soybean waste) along with four supplements (wheat bran, rice bran, corn flour, and gram powder) on growth characteristics (spawn run and primordial formation) and yield of Ganoderma lucidum. There were significant differences (P=0.05) in yield regardless of substrates and supplements used in experimentation. Among substrates, agriculture residues supported better yield and biological efficiency of G. lucidum compared to forestry byproducts irrespective of the supplements. The highest yield (82.5 g) and biological efficiency (27.5%) were recorded from paddy straw supplemented with wheat bran, which invariably resulted in significantly higher yield compared to the unsupplemented check(s) or other supplements used in this study.
