Abstract
Gas-exchange, plastid pigments and some other physiological parameters were determined in bean (Phaseolus vulgaris L. local populations) leaves naturally infected by Xanthomonas campestris pv.phaseoli (Smith) Dye, and Pseudomonas syringae pv.phaseolicola (Bukholder) Young, Dye et Wilkie, and in healthy leaves (control).
It was established that infected leaves had lower both plastid pigments content and photosynthetic activity as well as lower yield and quality of produce.
