Comparison of photosynthetic parameters in a collection of Portuguese common bean traditional varieties: settling the basis for drought resistance studies

Photosynthetic capacity of sixty Portuguese bean (Phaseolus vulgaris L.) landraces was studied. Net CO2 assimilation, stomatal conductance and transpiration were measured with IRGA. Chlorophylls and carotenoids concentrations were spectrophotometrically determined. Relative water content and specific leaf areas were also taken into consideration on the landraces comparison.
