Abstract
In a common garden, we investigated genetic and environmental influences on alkaloid production using Sanguinaria canadensis as a model. Nutrient and shade regimes were applied to replicated clones over one growing season, an d induction of alkaloid production in bloodroot was tested on a whole-plant basis using jasmonic acid as an elicitor. Alkaloid concentrations increase d with decreasing light intensity and fertilizer levels. Induction was not achieved by foliar application of jasmonic acid. Genetic influences represe nted by clone effects may be indicated by variation in alkaloid concentrati on by clone, but this experimental design did not allow us to distinguish g enetic from pre-experiment environmental influences on the rhizomes.
