Root respiration in winter wheat varies at different growth stages, affecting the carbon cycle in cropland. Researchers measured soil respiration rates in winter wheat fields and found that root respiration and its temperature sensitivity changed significantly during seedling, elongating, filling, and ripening stages. The study showed that root respiration was closely linked to soil moisture, temperature, photosynthetic rate, and root activity. The temperature sensitivity of root respiration also varied across growth stages, with the contribution of root respiration to overall respiration changing throughout the plant's development.
