Treatment of 2-week-old pea seedlings with 2 mg diuron/l resulted in a 25% increase in seed protein content. Increased cyclic photophosphorylation was observed in the chloroplasts of 3- to 7-week-old treated plants. The regulation of photophosphorylation in pea chloroplasts by diuron treatment is thought to control storage protein accumulation in pea seeds.
