Abstract: Abstract The regulation of hormones are shown in Lentinus edodes by wood shaving spawn culture. The growth and deyelopment of fruit-bodies can be promoted with various hormones.The biological efficiency of different concen- tration of gibberellin, tricaconfyl alcohol, C-751 and NAA to Lentinus edo- des was studied.The yields(fresh weight)of sporophores of Lentinus edodes had increased 41.4% and 39.7% than control with 1 ppm triaconfyl alcohol and 5ppm gibberellin respectively.On the other hand, increase of the yields with 6ppm IBA, 100ppm C-751 and 15ppm NAA sbared 24.9%, 17.8% and 5.1%. How-ever, It is no influence on the content of the major nutritions (carbohydrate, protein, fat) of Lentinus edodes.
