Research Abstract |
A reliable method to produce sufficient amount of conidia of Elsinoe ampelina was developed by modifying the concentration of the media. It enables us to evaluate the resistance of grapevines to anthracnose easily and stably. The resistance of 94 grapevines was evaluated, and the resistance of each vine was effectively shown by their lesion sizes. The hypersensitive response and the accumulation of brown compounds (phenolics) were observed soon after the invasion of the fungus in the resistant grapevine, and the further invasion into the plant cells was restricted. It was implied that the moderate resistant Vitis vinifera cultivars might have almost same mechanism against E. ampelina.
