Impact of temperature on photosynthetic rate
Witryna12 kwi 2024 · 3.2 Effect of wind speed on the photosynthetic responses of watermelon seedlings. The photosynthetic rate of watermelon seedlings was higher in plants exposed to 1 m‧s −1 wind speed compared to the control and Dini plants and was the lowest in the plants exposed to wind at 4 m‧s −1 for 10 h per day (Fig. 4A). WitrynaAt the optimum temperature, the enzyme is most efficient and the rate if maximum. At temperatures above 40°C the rate slows down. This is because the enzymes …
