Herbivore feeding and cyanogenesis in Trifolium repens L. [PDF]
Qualitative measures of herbivore feeding damage and cyanogenesis were obtained for 1000 Trifolium repens L. growing in unmanaged areas. An association between low herbivore feeding damage rating and cyanogenesis is indicated by the data. If only those plants given the highest feeding damage rating have significant reduction of vegetative growth and/or
