Photosynthesis is not affected by all environmental factors at a given time. You can relate the principle of limiting factors to the economics of enhancing the following conditions in greenhouses. Light intensity, temperature and the availability of carbon dioxide interact and in practice any one of them may be the factor that limits the speed (rate) photosynthesis. Clarifying the change from stomatal limitations… The environmental factors include light, availability of CO2, temperature, soil, water and nutrient supply apart from age of leaf, leaf angle and leaf orientation. Stomata are the channels by which plants exchange water vapor and carbon dioxide with the environment. Photosynthesis is influenced by both environmental and genetic factors. Limiting factors The rate of photosynthesis depends on temperature and the availability of light and carbon dioxide.
