Description |
Ganoderma lucidum (Fr.) Karst (Polyporaceae) is an important medicinal mushroom. Amongst three substrates, different moisture content, temperature regimes and pH levels evaluated for mycelial growth of this mushroom. Wheat straw + saw dust (1:1) with 70±2 per cent moisture content was ideal. The optimum temperature and pH for its mycelial growth was 30±1˚C and 5.5, respectively though the mushroom can grow in the temperature range of 30-35˚C and pH 5-6. Among three different doses of wheat bran evaluated as supplement, the dosage of 20 per cent was the best when wheat straw + saw dust (1:1) was used as substrate. Out of four base materials used for spawn production, wheat grains were most suitable. Studies carried on cultivation of G. lucidum during 2013 and 2014 on wheat straw + saw dust substrate supplement with wheat bran, amended with (3%) calcium sulphate and (1%) calcium carbonate, filled in polypropylene bags, sterilized, inoculated with (3%) wheat grains based spawn and placed in mushroom house in dark at 30±1˚C with high CO 2 and ≥85 per cent relative humidity, was optimum in terms of spawn run, pinhead formation, no. of fruit body, yield and biological efficiency. Two flushes were obtained in three months crop cycle and maximum biological efficiency of 28.7 per cent was achieved in supplemented substrate during 2013 cropping season. |
