New Study Reveals How Light Intensity Affects Soybean Leaf Respiration
The study looked at how different factors affect the CO2 compensation point in soybean leaves, which is related to photorespiration. They found that the CO2 compensation point and photorespiratory rate increase with higher light intensity. Phosphate limitation under strong light mainly causes the change in the CO2 compensation point. Certain substances like mannose and PEG raise the CO2 compensation point but decrease the photorespiratory rate. Aging leaves have a higher CO2 compensation point but a lower photorespiratory rate. This shows that photorespiration plays a significant role in the CO2 compensation point in plant leaves.
