过去,葡萄是用自根苗进行栽培的,自从葡萄根瘤蚜从美洲传到欧洲之后,几乎使欧洲葡萄园遭到全部覆灭。后来,查明了美洲野生种葡萄有抵抗葡萄根瘤蚜的特性,并因此培育成砧木品种,挽救了欧洲的葡苟栽培业。从此葡萄嫁接育苗法,便在全世界推广开来。一、日本的葡萄砧木研究动态日本于1912年开
In the past, grapes were cultivated with self-rooted shoots and almost all the European vineyards had been destroyed since the phylogeny of the grape phylloxera passed from the Americas to Europe. Later, it was identified that the wild American grapes had resistance to the phylloxera phylloxera and thus cultivated into rootstock varieties that saved the European cultivation.
