The regulation of photosynthesis by its assimilates was investigated in sunflower by altering the assimilate level in leaves by girdling, detopping, shading and defoliation. The level of assimilates like sucrose accumulated in leaves did not inhibit photosynthesis or Rubisco activity. Starch levels also did not have an influence on the photosynthetic rate.
