Effects of Net Photosynthetic Rate of Pteridium Aquiliumon on Temperature Increasing Progressively

In the temperature experimental condition, Pteridium aquilinum Net photosynthetic rate changes with the change of temperature. The optimal temperature is difference during different growing period, the optimal temperature is 21°C in just growing 1-5 days. The optimal temperature also increases with the Pteridium aquilinum growing, the optimal temperature is 23°C during just growing sixth days to primordial leaf, this correspond to it suitably grow under gloomy forest.
