In the early 1900s [[Frederick Blackman|Frederick Frost Blackman]] along with Gabrielle Matthaei investigated the effects of light intensity ([[irradiance]]) and temperature on the rate of carbon assimilation.

* At constant temperature, the rate of carbon assimilation varies with irradiance, initially increasing as the irradiance increases. However at higher irradiance this relationship no longer holds and the rate of carbon assimilation reaches a plateau.

* At constant irradiance, the rate of carbon assimilation increases as the temperature is increased over a limited range. This effect is only seen at high irradiance levels. At low irradiance, increasing the temperature has little influence on the rate of carbon assimilation.
