Abstract: Using wheat hybrid C6-38/Py85-1 and its parents (female C6-38 and male Py85-1) as materials, the effects and physiological mechanism of different planting densities on photosynthesis of flag leaf and grain yield were analyzed. At different density levels including low (L, 150 plants/m2), middle (M,
