Abstract: The effects of fungi of Helminthosporium on the contents and productions of resveratrol and polydatin in the seedling of Rumex gmelini were studied. The results showed that the specialization of polydatin to fungi in the seedling of R. gmelinii was not obvious and there are some relativity between the effect and the concentration of spore suspension. Resveratrol showed some selectivity to fungi. Different strains of Helminthosporium turcicum Passerini had different induction effects and mainly acted on the starting time. Little inhibition effect of various treatments on biomass of the seedling R. gmelinii was observed during the 0-50 d. H. turcicum Passerini 001 could induce the production of polydatin and resveratrol in the seedling R. gmelinii, which increase 1.54 and 3.99 folds, respectively, to the contro1 ones at the strongest induction conditions.

Key words: resveratrol, polydatin, fungi of Helminthosporium, Rumex gmelini Turcz., fungi induction
