摘　　要：香菇出菇不同阶段的ＡＴＰ含量、无机磷含量及ＡＴＰ酶活性有相应的变化，菇蕾形成时ＡＴＰ含量骤然下降，每克干组织的ＡＴＰ比原基形成时下降５．８倍，而Ｃａ２＋－ＡＴＰ酶及Ｍｇ２＋－ＡＴＰ酶的活性在菇蕾形成前表现为最高，菇蕾形成后均明显下降，说明菇蕾形成时，ＡＴＰ被大量地水解利用。无机磷含量也以菇蕾形成阶段最低，这和ＡＴＰ的合成与分解作用有关。Changes of ATP content, Pi content and ATPase activities in different fruiting stages of Lentinus edodes were measured. It was found that the ATP content of primordium decreased by 5. 8 times throught the first stage to the last stage. The activities of Ca2+ ATPase and Mg2+-ATPase were highest in the third stage, they decreased greatly in the last stage, this indicated that the last stage of fruiting procedure required a large amount of energy. Pi content was lowest at the third stage, this could relate to the decomposition and synthesis of ATP.
