Abstract
In the leaves of both greenhouse- and in vitro grown potatoes (Solanum tuberosum) irradiation with UV light induced the biosynthesis of the stilbene phytoalexin trans-resveratrol. The stilbene could be detected after induction by UV light with the help of HPLC in all genotypes tested (six cultivars, one breeding line). The trans-resveratrol concentrations in the leaves 2 days after induction reached a maximum and declined thereafter. Between genotypes differences existed with regard to the amounts of trans-resveratrol accumulated following induction.
