Accumulation of dry mass, total N, protein N, and soluble amino acid N in the developing fruit and seeds of bell pepper (Capsicum annuum L.) was determined at selected intervals following anthesis. The importance of photosynthesis to the growth and nitrogen (N) assimilation in the developing fruit wall plus placenta (FWP) and seeds was evaluated by comparing the growth and accumulation of reduced N in nonphotosynthetic and photosynthetic fruits (covered vs. uncovered). The growth rate of the FWP and seeds was similar under both conditions. After 65 days of growth, the fruits kept in the dark weighed about 15% less than those receiving illumination; seed weight was the same for both treatments. Total N content of the FWP or seed continued to increase up to 55 days after anthesis. The FWP accumulated over 90% of fruit's total N, and there were no significant differences between covered and uncovered fruits. Protein N accounted for about 50% of the total N present in both covered and uncovered fruits. 15 references, 2 figures, 2 tables.
