Negative Relationship of Stomatal Size and Density with Resistance in Sugar Beet to Cercospora beticola. E. G. Ruppel, Research Plant Pathologist, Plant Science Research Division, ARS, USDA, Crops Research Laboratory, Colorado State University, Fort Collins 80521; Phytopathology 62:1095-1096. DOI: 10.1094/Phyto-62-1095.

Resistance to Cercospora beticola of sugar beet heart leaves as compared to susceptibility of mature leaves on the same plant was not related to size of stomatal apertures, nor to density or stomatal movement. No association was found between degree of resistance and size of apertures or stomatal density in six sugar beet cultivars.
