生姜产品形成期叶片光合最适温度为２５℃，此温度下光合速率和表观量子效率最高。光合速率在一定范围内随光量子通量密度和ＣＯ２浓度升高而增加。生姜叶片的光合作用光补偿点在２５～６９μｍｏｌ·ｍ－２·ｓ－１之间，随叶温升高而升高，且叶温越高上升幅度越大；光饱和点为６４２～８６７μｍｏｌ·ｍ－２·ｓ－１，在１５～２５℃范围内随叶温升高而升高，超过２５℃，则随叶温升高而下降。ＣＯ２补偿点和饱和点分别为２５～７２μＬ／Ｌ和１３４３～１５６６μＬ／Ｌ，均随叶温升高而增加，且高温条件增加幅度大。
The optimum temperature for leaf photosynthesis during ginger product formation was 25 ℃, and photosynthetic rate and apparent quantum yield were the highest at this temperature. The photosynthetic rate increases with the increase of photon flux density and CO2 concentration within a certain range. The light compensation point of photosynthesis of ginger leaves was between 25 and 69μmol · m-2 · s-1, increased with the increase of leaf temperature, and the higher the leaf temperature, the higher the amplitude of light saturation. The light saturation point was 642-867μmol · m- 2 · s-1, which increased with the increase of leaf temperature in the range of 15 ~ 25 ℃. When the temperature was over 25 ℃, it decreased with the increase of leaf temperature. CO2 compensation point and saturation point were 25 ~ 72μL / L and 1343 ~ 1566μL / L, both increased with the increase of leaf temperature, and high-temperature conditions increased marginally.
