The word spawn is derived from an old French verb, espandre , meaning to spread out or expand. Spawn is also defined as “the mycelium of fungi, especially of mushrooms grown to be eaten, used for propagation.” The effects of bag spawn to sawdust substrate on the growth of Pleurotus ostreatus were conducted. The duration of mycelial growth and days of pinhead formation of bag spawn(2.5kg) were 18~19 days and 7~8 days, whereas bottle spawn (1,000㎖) was 18 days and 6 days, respectively. The yield of mushroom fruitbody was that bag spawn is 100~118g, bottle spawn was 95~115g. In economical analysis, bag spawn is increased to 50%, compared to bottle spawn in relative income.
