Cyanogenic Plants Of Illinois, Kevin E. Aikman

Masters Theses

Cyanogenesis in 50 species of vascular plants collected from east central Illinois was studied by examining 10 populations of each species. Each population consisted of 30 individuals, which gave an over all sample size of 300 plants per species. Herbarium specimens from the Stover Herbarium of Eastern Illinois University (EIU) were also tested for the presence of cyanide. More than 20,000 specimens were tested for this study which included cultivated plants, introduced weeds, and native plant species. The speed and degree of the HCN reaction as well as the specific plant part tested were included to give a more specific …
