Abstract
The potential induction of phytoalexin production by stress following exposure to ozone, sulfur dioxide and several herbicides was evaluated in bean (Phaseolus vulgaris L.) cultivars and lines varying in sensitivity to ozone injury. The isoflavonoids, coumestrol and several other coumestans were extracted from leaf tissue after various periods of exposure to ozone, sulfur dioxide or application of various herbicides. Elicitation of isoflavonoid production varied with lines and cultivars, but generally increased with increased plant injury caused by ozone, sulfur dioxide or herbicide.
