Ozone injury on Phaseolus vulgaris (common bean): Bean Biomonitoring Protocol

Experimental aim:

• To demonstrate whether ambient ozone concentrations cause visible damage to sensitive crops.
• To identify the extent of occurrence of visible injury on ozone-sensitive and ozone-resistant Phaseolus vulgaris in the differing ozone and physical climates.
• To quantify the reduction in pod yield of the ozone-sensitive Phaseolus vulgaris (but this might not be possible in very hot conditions, as pods will not develop).
• To establish a flux-effect relationship for the ozone-sensitive and ozone-resistant Phaseolus vulgaris – we now have sufficient stomatal conductance data for developing a flux model, but if possible we would like to validate the model in differing climatic conditions.
