Abstract
Light and nutrient availability jointly affected the concentration of 4 of 6 furanocoumarins present. Both nutrients and light were limiting factors in furanocoumarin production insofar as low availability of either resource limited the effect of variation in the other resource. Relative amounts of the furanocoumarins were independently influenced by light and nutrient availability. UV radiation increased the concentration of all but 2 of the furanocoumarins and also influenced the relative amounts of furanocoumarins. Since furanocoumarins are UV-phototoxic to many organisms, including insects, the response of Pastinaca sativa to UV radiation may affect their resistance to herbivores.-from Authors
