Abstract

Research on the effect of weight and composition of media, temperature and chemically stimulation on fruiting body formation of shiitake (Lentinus edodes) had been done in Wamena, Jayawijaya district, Irian Jay a. The research consisted of three experiments. The first experiment consisted of 3 kinds of media such as media A, B and C(A- sawdust and 100% standard nutrition; B = sawdust and 50% standard nutrition; and C = sawdust without nutrition) and three kinds of temperatures were 20°C (room temperature),4°C (refrigerator temperature) and -10°C(freezer temperature).The second experiment used 4 kinds of media. They were media D, E, F and G which were stimulated by SnCh, CoCh, salicilic acid and the extract of bark of "Seno" (Castanopsis acuminatissima).The third experiment used medium B, weight 500 g and 1000 g (medium H and I).The result showed that medium H& I produced the highest fruiting body. However medium I produced the higher fruiting body compare to medium H).The added of the extract of the bark of C. acuminatissima.SnCh, CoCh and salicilic acid stimulated the fruiting body formation
