External factors
- Light: Three parameters are considered within light, Light quality, intensity and duration of exposure. At lower intensity of light, a linear relationship exists between the incident light and CO2 fixation rates. At higher intensity of light, there is breakdown of chlorophyll which leads to the reduction of photosynthesis. Light is rarely a limiting factor because light saturation occurs at 10 per cent of the full sunlight.
