Roots of celery (Apium graveolens) and parsnip (Pastinaca sativa) were inoculated with Sclerotinia sclerotiorum. At the beginning of the infection it is recognized that the level of furocoumarins rises but decreasing in the further time. Trimethylpsoralene was detected neither dc nor hplc. Sclerotinia grows poorly in parsnip. In this the high level of furocoumarins prevents the growth of the fungus because the furocoumarins are fungistatic. Obvious Sclerotinia is able to stimulate the origin of furocumarins in genetic predestinated plants first at time which can explained as reaction against the infection. The infection cannot avail to arise the technical useful yield.
