5.2 - Crop Yield
Related to the:
rate of photosynthesis - this is the combination of CO2 and water with light (enzyme) to form glucose (starch) and oxygen
- Increasing the concentration of CO2, CO2 is the substrate
- Shown in graph - rate of ps will increase the yield until the greatest yield point
Temperature - Increasing
- Shown in graph - rate of ps increases as temperature increase up to an optimum (peak) temperature
Increasing temperature in a greenhouse can also avoid frost damage and provide constant temperature - both contribute to increase in yield
Both have limits (optimums)
