Effect of Mould on Biological Efficiency of Ganoderma Lucidum (Leyss. Ex Fr. Karst)

In Haryana condition, studies carried on cultivation of G. lucidum during 2013 and 2014, a combination of wheat straw + saw dust (1:1), having a 20% dosage of wheat bran as supplement and amended with calcium sulphate (3%) and calcium carbonate (1%), was filled in polypropylene bags, plugged, sterilized and inoculated with wheat grains based spawn @ 3%. The bags were placed in mushroom house at 30±1˚C with 90±1% relative humidity. During cultivation mould incidence was less in supplemented substrate (10.00%) as compare to un-supplemented (14.00%) substrate for two consecutive years and which resulted in lower down the biological efficiency from 27.52% to 20.18% respectively.
