本文以 A chnanthes sp.为例，通过测定其光系统II的量子产率的变化，间接分析高温热胁对其生长与消亡的影响。结果表明，光量子产率对高温胁迫有较强的响应，整个电子传递步骤的影响可以通过其变化反映出来。 A chnanthes sp.的最适温度范围为15℃～35℃，适温范围比较广，自然条件下温度对其光合活性影响较小。故而自然条件下高温不是其消亡的主要原因。

In this report ,the effect on the stress to Achnanthes sp. led by high temperature was ana-lysed through the changs of photochemical quantum yield in photosystem II.The result showes that yield have a stronger response to heat stress ,the electron transfer step influence can be reflected through its changes. The most suitable temperature range of Achnanthes sp. may be 15℃-35℃.So high temperature is not the main reason for the water bloom of Achnanthes sp. demise under natural conditions.
