Abstract
Grapevines have been known to express their own defense systems to protect themselves against foreign pathogen attacks. To investigate the defense responses in grapevines against downy mildew and anthracnose, the change patterns of salicylic acid and resveratrol contents were evaluated by high performance liquid chromatography in grapevine leaves after pathogen inoculation or culture filtrate treatment of Elsinoe ampelina. The contents of salicylic acid and resveratrol started to increase sharply within 1 h after inoculation of resistant cultivar ‘Campbell Early’, but there were little content changes in the cultivars, ‘Rizamat’ and ‘Kyoho’, susceptible to downy mildew and anthracnose. Similar change patterns in salicylic acid and resveratrol contents were observed in cell free culture filtrate treated with anthracnose pathogen. Therefore, it is considered that the differences in resistance to downy mildew and anthracnose among grapevine cultivars are closely related to the production of salicylic acid and resveratrol in their stems.
