“…Singh and Waraitch [18] also reported reduction in protein content in diseased leaves of sugarcane by Colletotrichum falcatum. The total nitrogen and protein were decreased in bell pepper diseased leaves but Jeyarajan and Ramakrishnan [19] studied potato virus Y infected chilli leaves and found total nitrogen, protein N and amide N contents increased and the nitrate N decreased compared to healthy leaves, but ammonium N and non protein N levels were not affected. The superoxide dismutase enzyme activity (SOD) was very high in healthy leaves compared to diseased leaves during present investigations whereas on contrary Scandalios [20] observed an increased SOD activity in tissues of oat at 40 h with Drechslera arenae but no such increase was observed in oat leaves inoculated with D. nobleae by Gonner and Schlosser [21].…”

A study using susceptible cultivar (cv Bombay red) to D. bicolor grown under inoculated (infected) and noninoculated (healthy) conditions in the field at Department of Plant Pathology (R. C. A.), Udaipur. Data were recorded on different physiological parameters i.e. chlorophyll 'a', total chlorophyll, carotenoids content, chlorophyll stability index, photoactive radiation, leaf temperature, leaf area index and photosynthesis decreased in the infected plant compare to healthy plant while chlorophyll 'b', membrane permeability, transpiration rate, cuvette temperature, stomatal conductance, internal CO 2 concentration, relative humidity and vapour pressure deficit increased in the infected plant compare to healthy plant. In addition, total sugar, mineral status, water status were also decreased in the infected plants compare to healthy plants. However, the superoxide dismutase enzyme activity was very high in healthy plants compared to infected plants. These results indicated that the maintenance of physiological function during leaf blight infection could result in improved bell pepper yields under diseased conditions.

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.
