Evaluation of Sawdust and Woodchips Substrates of Different Tree Species on Sporophore Production of Ganoderma lucidum

Production of Ganoderma lucidum using sawdust, woodchips and combinations of three tree species viz. shisham (Dalbergia sissoo), mango (Mangifera indica) and jamun (Syzygium cumini) as substrates, with three strains namely G-1 (OE-62), G-2 (OE-52) and G-3 (local isolate) was investigated in the laboratory of SKUAST-Jammu during 2009-2010. The results suggested that shisham tree (Dalbergia sissoo) sawdust or woodchips or their combination produced significantly higher biological efficiency over other two tree species, irrespective of the strains tested. The maximum biological efficiency (16.93 per cent) was obtained from the formulations constituting sawdust and woodchips of shisham in 1:1 ratio. Strain G-1 (OE-62) proved to be best that gave maximum biological efficiency of 19 per cent on formulation of shisham sawdust and woodchips in 1:1 ratio.
