研究了3种美国葡萄和3个葡萄品种对UV-C辐射的植保素生产潜力。研究了短时UV-C辐射后3d内白藜芦醇、鬼臼草苷和蕨类成分含量的时程变化。结果表明，白藜芦醇和白藜芦醇脱氢二聚体是响应UV-C诱导积累的两种主要二苯乙烯类化合物，两种化合物的浓度通常达到>；100mgg/g鲜重。相比之下，白藜芦醇和蕨类化合物的产量一直很低。根据所得结果，讨论了二苯乙烯类植物保卫素在葡萄抗病中的作用。
The phytoalexin production potential of three American Vitis species and that of three cultivars of Vitis vinifera were evaluated in response to UV-C irradiation. Time course changes in resveratrol, piceid, epsilon-viniferin, and pterostilbene contents were studied within 3 days after a short UV-C irradiation. Results show that the two major stilbenes accumulated as a response to UV-C elicitation are resveratrol and epsilon-viniferin, a resveratrol dehydrodimer, the concentration of both compounds usually reaching quantities > 100 mu g/g of fresh weight. In contrast, piceid and pterostilbene were constantly produced in low quantities. Owing to the results obtained, the role of stilbene phytoalexins in the resistance of grapevines to diseases is discussed.
