Optimum photosynthesis temperature

WebPlants can photosynthesise over a wide range of temperatures from 0°C to around 50°C. The optimum temperature for most plants is 15°C to around 40°C. Temperature affects the … WebJan 14, 2024 · The results were alarming. The researchers found that temperature “peaks” for carbon uptake—18 degrees C for the more widespread C3 plants and 28 degrees C for C4 plants—are already being exceeded in nature, but saw no temperature check on respiration.

Effects of temperature on photosynthesis

WebThe response curve of net photosynthesis to temperature is different from those for light and CO 2. It shows minimum, optimum and maximum temperatures. Between the C 3 and C 4 plants, while the former species have optimal rates from 20-26°C, the latter species may show optimal rates from 35-40°C.
