Abstract
Photosynthetic characteristics of soybean leaves infected with Pseudomonas syringae pv. glycinea were investigated for 8 days. The difference in photosynthesis rate between healthy and diseased soybean leaves decreased for 2 to 4 days after inoculation and then increased. In respiration rate, healthy and diseased leaves showed the same tendency as photosynthetic rate. The stomatal resistance increased following Pseudomonas syringae pv. glycinea infection. The total chlorophyll content of the infected leaf was less than that of the uninfected. Pseudomonas syringae pv. glycinea infection induced the malformation of stacked grana in chloroplast. Dry matter production declined after infection.
