Influence of air permeability on growth of Cordyceps militaris
Cordyceps militaris was cultivated in four kinds culture bottles covered with different permeability materials,in order to studied the effect of air permeability on the growth of Cordyceps militaris.The results showed that the air permeability has significant effect on the mycelium growth,primordium formation,fruiting body growth and so on.The higher the air permeability was,the shorter the time for mycelium cover and primordium formation,and the faster the fruiting body average growth speed was.Meanwhile,the fruiting body fresh weight was heavier and biological efficiency was higher.Therefore,good air permeability could promote its myeelium growth,primordium formation and fruiting body growth.The Hydrophobic Fluompore Membrane iS the most ideal covered material for cultivating Cordyceps militaris in bottles.
